Crack flapping is the act of slamming your and your significant other's asscracks together in a fit of sensual joy.
The old lady and I got hot and heavy last night, and we started crack flapping. I came so hard I farted inside her.

Get the the egg about to crackmug. When your having anal sex and you slip your dick through a slice of American cheese and continue to rupture her anus, hence the name, cracking the bun off the cheese.
An example for Cracking the bun off the cheese:
“Yeah Susan, Earl was taking me down to pound town and then he grabbed a slice of American cheese and stuck it in the wrong hole and he cracked the bun off the cheese.”
