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.

the hot musky sweaty and maybe a little shitty residue left on the asshole after going toilet and not wiping very well which gives off a strong smell and can be very tasty

Someone who is bad at everything but always tries to ruin the day of others. Basically a Sell-Out, but 10 times worse.

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.
