It usually means that he wants to have sex with you.
He wants to have a sexual intercourse with you
it means he's a gentleman! (:
Either it was an accident or he really likes you.
Either it was itchy or he got a BONERRR!!
It means that that guy really loves you and it's also really bad so don't let a guy do it to you.:)
If you're ugly be happy. If you're pretty punch him.
it may meen that he likes u :D
He wants to draw your attention to himself.
it means he wants to kiss you
You should just go along with it and touch him up too.
A guy may rub a girl's waist if he likes her. A guy may also do it accidentally when walking by and it may not mean anything.
