gack in the crack

The substance in between a man's ass cheeks that creates skid marks. Also known as butt butter, gack in the crack is usually formed as a result of several components put together. These are:
1) A hairy ass
2) A moist defecation followed by clean up with cheap TP
3) Physical exertion that causes the hairy ass to perspire

Mike took a hurried dump in the portajohn outside the stadium and then went back to tailgating. It was a long walk back to the pickup and the hot weather made him sweat. By the time he got back to the beer cooler he had some gack in the crack.

crappy crack 

Crappy Crack is when you have wiped your ass after taking a crap earlier in the day.. As a result you spread your crap higher in your crack. When you use the toilet a second time you find that you have left a skid mark on the back of the toilet seat.

You have swamp and gremlin ass and you wiped it higher in your ass crack and you sit down on the toilet seat and leave a crappy crack (toilet seat skid mark).

gut crack 

The opposite of “butt crack.” Where a person with a large gut wears a shirt that is either too small, or purposely wears a top to expose their mid drift while ignoring the fact that they don’t sport a “six pack” set of abs. Instead, it’s obvious to everyone but them, that they’ve drank one too many six packs and should either hit the gym or buy a shirt that fits.

Look at the gut crack on that chick!
