Get the Sog the Bunmug. 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.”

Get the free-bunningmug. 
Used to refer in a playful way to someone that has little to no buttock definition. The word comes from the struggle of trying to work out the glutes and still being unable to reach the desired fullness or definition.
