crust pants 

Old pants that have started to fall apart, so you put patches on to keep them from disintegrating. The patches consist of random fabric and crust punk band patches. The pants are also rarely ever washed, but must be washed by hand when they are.

Cool dude: "Woah did you see his crust pants?"
Another cool dude: "Yeah! His pants are pretty dope."

crusty pants 

Jocular term for a derelict, wineo, street person, or others not known for impeccable hygiene--a bum. These people never remove their trousers, because they are so infested with vermin and microbes that they might wander off by themselves, leaving the bum naked. Few things are more frightning than encountering an empty pair of animated pantaloons in a dark alley. And no, I've not been drinking.

Upright Citizen#1:"Who's that crusty pants waving at us?"
Upright Citizen#2:"That's just Mayson, the town drunk."
Upright Citizen#1:"But this is Los Angles."
Upright Citizen#2:"He always was ambitious."

Crusty pants 

When you have a poop and if you don’t wipe properly the poop will cause skid marks and when it dries the poop will go crusty which results in crusty pants

Mommmm I have crusty pants again
