When something is messed up, not right, jacked up, not cool or not fair its a crumble. It can replace any of those sayings.

Whenever you don't know the answer to something, or just want to confuse someone use this word. It is the adult equivalent to the word, 'smurf'
We were at the park and there were a lot of crumbly people there - or - what's wrong? You look crumbly!

A person who is exceedingly annoying and probably the world's worst person. DO NOT ASSOCIATE WITH CRUMBLY PEOPLE.
Man, that tall Asian girl who hangs out in room W719 and bakes things, and uses that one cabinet next to the cups is awful crumbly. I hate that bitch. Worst person ever.

Used to describe something that is decadant and well recieved. Pertains to the crumb-like nature of delicious baked goods.

When having sex for the first time in a while (usually because you are a loser) and the debris in your pubes "crumble" and fall off/out of your pubes. Debris such as dandruff, dust, mold, dirst, and in some cases dried cum from uncontrolled masturbation events.
Girl 1: So i heard you had sex last night
Girl 2: Yeah but it was obviously the guys first time in a while
Girl1: Why, did he crumble?
Girl 2: He crumbled the whole time!
