A foul smelling mixture of dead skin cells, dirt, sweat and shit seepage from one's asshole, collecting in the ass crack.
I would have let Sara give me a rimjob, but my crack was full of ass cheese because I hadn't showered for days.

You call someone an "Ass Cheese" when they do something really dumb that pisses off everyone. This word was invented during Lunch recess at Zion Heights Middle School when SOMEONE kicked the class 8-1's only volleyball over a fence.
George(fake name) : *Kicks volleyball over the fence during lunch recess*
John(fake name): Great Job you !@#%ing ASS CHEESE!!!!
George: Duuuuuuuh
John: *beats up George*

When you shart in your pants and your in such a situation that you can't immedietly get somewhere to change your underwear or you don't realize there is actual poop fermenting inside your pants so you don't think to change your undergarments or you don't care enough to change your underwear. The stinky fart solution saturates your underwear and begins the aging process much like aged cheese.
"I went on a camping trip and accidently sharted. I didn't have an extra change of clothes so I had Ass Cheese growing in my shorts."

Someone who is bad at everything but always tries to ruin the day of others. Basically a Sell-Out, but 10 times worse.
"Minning screwed up at Volleyball so he kicked the volleyball over the school fence. He is such an Ass Cheese."

Dick cheese is what forms when you nut in someones ass, then insert a butt plug. Do this multiple times and the cum will start to ferment into dick cheese.

The act of cumming inside her, letting it set for a minute, then sticking your dick back in and moving it around to curdle it. The result of what she shits out is Ass Cheese.
