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.
