When a guy pins a girl (or boy) to the ground with his legs, and straddles her while clamping her body ... then continues to whack her on the head with his cock (also known as cock slapping).
While wrestling, Jimmy ending up giving Sally a nice clamp slapper!
When she bothers me I just threaten to clamp slap her.
1. Your mom when you are little and try to get into the cookie jar or touch her expensive vase from India.
2. A bitch/asshole that doesn't want you to touch their goods.
Hey at least your mom lets you eat cookies whenever you want, mine is just a mean hand slapper!
Dude: Hey dude, that hottie at the end of the bar is stupid fly.
Friend: Man, I wouldn't touch that bitch, she's a hand slapper.
