Punch, kick and hang them or just literally hit him where it hurts
Tell him?
Tell him exactly this if he can take a hint "I cannot give you what you wish so lay off" It works unless the guy is dumb then just tell him to lay of or swear at him and tell him to leave you alone.
it means they dont like you
Tell him to back off!
Many show off as a form of flirting. If a guy does things in order to get your attention, he is doing both.
Knowing a guy is being to touchy is when you are starting to feel uneasy. This is when you need to tell the guy to back off.
tell him he is not your boyfriend and to back off.
suck him off
Pick your nose and eat it. Or just tell him outright you're not into him. As a guy, let me tell you - our minds will ignore subtlety. Don't be subtle.
as long as you show the guy that u like him then its a turn on
you can either go up to her and tell her to back off alittle cause you really like him or you can tell they guy how you really feel.
it means he want to show off to his friends he has a girlfriend
