A form of masturbation or "wanking". The male rubs his penis on the bed to masturbate. It is a faster way to approach a male orgasm, because it is rubbing the penis harder than a "hand job" due to more pressure exerted onto the penis.

when you think someone or something is stupid, you chin rub.
normally you look at them like they are stupid and rub your chin hinting that what they just said is dumb. but when you cannot see the person or do not feel like rubbing ur chin like you have a beard you say chin rub so people know thay wat they said was amazingly stupid and idiotic.

To jack off or masterbate. It origin comes from the vibrant red color the penile shaft takes on after a particularly vigorous rub-out session.
