Deef

An incredibly noisy and smelly poop, mostly dropped at the exact time someone else wants to use that specific toilet.

I thought I heard the Fourth of July firework show start two hours early, but then I realized David was just taking a massive deef.

That chinese food from the end of semester dinner had our entire suite dropping deefs all weekend long.

Deef

1. That of which is deeferent or different. Often times meaning strange or weird.
2. One who claims themselves to be different, individual, unique, or nonconforming. Deefs are usually marked by black clothing, tight clothing, dickie pants cut into shorts, converse shoes, and/or patches on one's backpack.

All of those deef kids sit on the hill with the patches on their backpack and dickie cut off shorts.
