It doesn't really mean anything. Maybe his hands are cold, maybe he's awkward and doesn't know what to do with his hands. It's possible that it's a “Tell”, that he's awkward specifically because he likes the girl, so he's try to keep his composure. But, by itself, it's not much to go on.
It may be because they're feeling nervous or shy, and putting their hands in their pockets is a way to feel more comfortable and relaxed.
Putting your hands in your pockets indicates insecurity and meekness. Sometimes, of course, this is just an attempt to get more comfortable, but trying to get more comfortable is also something one would do if they were feeling uncomfortable or insecure.
It is not a friendly thing. It is a sign that he is attracted to you. Usually, when guys are attracted to somebody, they use the sense of touch to test you or to see if you feel the same.
What it Means: When a person is confident and ready for action, you may see them strike this pose. It's also a way of showing there are “issues,” “things are not good,” or “I am standing my ground” in a territorial display3.
Prolonged eye contact, raised eyebrows, and dilated pupils are all evidence of attraction. A person might lick or bite their lips or look at your lips if they're attracted to you as well. Open body language and facial expressions are also signs a guy or girl is feeling attraction towards you.
Here are the typical signs someone is attracted to you:
They tilt their head as you speak (a sign of engagement). They smile at you. They make eye contact with you. They reach out and touch your arm, hand, back, or leg.
Well, this hug is a perfect way of telling how intense your sexual attraction is for one another. So, when your partner grabs your lower back while you hug them, it means that your partner is ready to tell you how they feel about you without any feeling of shame.
He's showing his affection for you.
Being affectionate could mean holding your hand when you are walking together or when you are having something to eat. A guy will often do this to reassure you that he likes or even loves you. If he interlaces his finger it means he is really into you.
“The heart-hand symbol means something between 'I love you' and 'thank you,' ” the country singer Taylor Swift said in an e-mail from her “Speak Now” tour.
"When people keep their hands in their pockets, it appears they are hiding something. And someone is more likely to be lying because they are hiding their hands," she explains. Concealing your hands comes across as more controlled, which can be interpreted as "deceitful and untrustworthy," she notes.
Guys subconsciously default to this position when they relax because they feel more at ease with their essential organs out of harm's way. “You could think of the hand there like insurance against a friend who might give them a nut jab or a kid who accidentally hits a ball at them,” says Van Edwards.
Practice Proper Posture: Standing or sitting straight with your shoulders back and your head held up, nonverbally reflects your confidence. It doesn't matter how tall you are, when your posture is straight and aligned, instead of shoulders slumped and head down, you will appear in control and confident.
He's being affectionate.
Whether you're platonic pals or something more, he could just want to show you he cares about you—nothing more to it! A hug could be his way to show he likes you and wants you to feel special. Actually, studies indicate that the more hugs we get a day, the happier we are.
A hug for declaring his attraction toward you
So what does it mean when a guy hugs you with both arms around the waist? This type of hug is the surest sign of attraction there can be. Hugging you around the waist and pulling you in is an indication that he wants you, romantically or sexually (or even both!)
He'll Touch You Back
He might not touch back, but if he does, you've definitely got the green light. Men who are attracted to you might even engage in more touch. If a man actively tries to touch you during your interaction, it may mean he wants to get closer to you or close the distance between you two.
He touches you often
Does he tend to pat your hand or arm when talking? The more he touches you, the more he loves you. Men probably tend to touch you unobtrusively and non-sexually if they're into you. A simple touch can convey a more striking and direct message than many words.
Interlocked fingers: When couples interlock their fingers, it shows a deeper connection, and that the person is more vulnerable and emotionally and physically connected at that moment. Non-interlocked fingers suggest a more casual relationship.
Generally, the lower the hands, the higher the physical attraction. If their arms encircle your waist and they press their hands against your lower back, that might be a romantic hug—especially if they draw your lower body in closer to theirs.
Remember to keep the physical contact quick and light for hugging friends. Anything more prolonged might be misinterpreted as romantic. Lean in, bending from your waist. The idea here is not full-body contact, which is a much more intimate and personal hug.
Wrap one hand behind his back, just above his butt. Place the other hand around his neck so that your fingers rest where his neck meets his shoulder. Lightly grab onto the left side of his neck (his right side) with your left hand. If you're extra romantic, you can lightly tousle the back of his hair with your fingers.
Guys that are into you often use lots of emojis, text first, or even double text. Watch for in-person signs, like holding eye contact, respectful little touches, or leaning in close. A follow-up text after a date or hangout, or a raincheck when he can't make it are sure signs that he wants to spend more time with you.
