Ass crack 

The thing you yell when nothing else comes to mind. One of those times when you're so mad that you say something extremely irrelevant and that doesn't even make sense, when you could have just as easily said ass hole.

Tracy: Yeah, thats such a dumb thing to say no one cares.

Tracy: A what?

make a crack about 

Make a crack about means to laugh at or make fun of something that is interesting or tell a joke on someone

From Family Guy Seaonn 2 Eposide 2
superman: I killed a hooker. She made a crack about me being faster than a speeding bullet.

I just met this girl yesterday who thinks she's hot, but a lot of my friends make a crack about her being such a butterface

Sack Whack on the Back Crack 

The act of thrusting the man junk so far into a woman's (or man's if you are homosexual) anus multiple times that the balls consistently slap against the "host's" butt cheeks making a sound like a great high five.

ChadKant: "you wouldn't want to."

Zenovia's Playa: " YEAH! BECAUSE CHAD GAVE YOU THE sack whack on the back crack WHILE YOU WERE SHIT FACED DRUNK LAST NIGHT AND PASSED OUT ON THE COUCH!"
