anal smashing 

means to have your ass smashes hard, to have extremely rough aggressive anal sex, usually only tramp stamp type girls are okay with a total anal smashing doggy style because they know there pussy already no good no more.

I met a girl with a tramp stamp at the bar last night and she told me to give her a good hard anal smashing.

Stoshing 

When a guy shoves his dick down a bitch's throat, except instead of doing it for sexual pleasure, he does it because she needs to shut her fucking mouth.

Bitch 1: "Yeah, well, you know what? I can't let you in, the website specifically said come ready, that means have the money ready. I can't wait for you to count it."

Guy 1: "Man is she a bitch with a big mouth."

Guy 2: "Yeah she needs a good stoshing."

smashing fat chicks

Smashing Fat Chicks: to smash a chick of at least double the male counterpart's weight (obviously, more is preferable). The skankier, the smellier, the hairier the trick, the better. Also, must be willing to roll out on a moment's notice.

Smashing Fat Chicks: "Trick, you better be willing to let me smash your skank-ass-hairy-smelly-trick-bitch booty before we roll out to do some ass-to-mouth while I drive your bitch-ass to the salon so you can trick up your fat 'do."
