1. A word used to describe a real annoying shithead
2. A word used when frustrated, and wanting to avoid swear word, with an extra "AH" pronounced on the end.
1. This guy stole my nail clippers. Whatta poozah.
2. *A little kid runs into a clown, who crashes into a t-shirt stand, which rolls down a hill, which triggers a button in a nucleur power plant, creating a chemical reaction, blowing up the world and killing everone except a laid-back man and a nun.*
Not want to act rude infront the the nun, the man needed a non-swear word to express his frustration concerning the incident.
Man: *sigh* "POOZAH!"
