Phencyclidine - aka PCP or "Angel Dust". Can be used to refer to other types of drugs, particularly when used as an adjective (eg "I was zooted last night...") but in NYC at least traditionally meant PCP.
The outfit that rowers wear. A one piece, tight fitting suit, that looks like they are wearing bike shorts and a singlet top. They are tight fitting to allow rowers to move without restriction or catching their clothing on anything. You will often hear rowers comment/complain of a zootie-tan. Can also be refered to as a zoot-suit or a uni.
"Look at that rower's zootie, you can see every muscle bulging!"
