Get the crustiesmug. Crusties are very proud of their state of filth. A step on you'll find the unwashable. Unwashables truely and deeply loath any form of personal hygiene. An unwashable is a religiously hardcore mysophile who usually stays unwashed & crusty all his life. For them it is not so much a temporary statement of believes as a dedicated way to live, despite often being shunned by society.

Get the Crustymug. The organic matter dried and caked onto the mouthpiece of a bong. Often times bong crusties appear after using the pipe for many days/weeks/months without proper cleaning; also a side effect of too many people sharing one piece.
Dude!#@ Clean those crusties off before you pass The Chuggler. I don't want your gnarly mouth herpes on my piece!

Get the crustiesmug. Similar to a dingle-berry, a crusty cling-on is a dried up piece of poo that gets caught up in an unkempt and unwashed hairy ass of a man. Or a woman that has a hairy ass, though that's more of a rarity.
Dude I used a whole roll of toilet paper after the dump I left in the can last night but still got crusty cling-ons hanging off my ring beard!
