noun-A wild, vicious creature discovered in 1982, indiginious to the Metro-NYC area who enjoys Burger King, drawing penis in a marble composition book, and envying his brother. The creature tends to be in the vicinity of 01' Hyundai Tiburons, especially rusty ones. The Seabury should only be aproached if you have Disaronno or Captain Morgan readily available. Also beware of the Seabury's anger issue.
"There's a wild Seabury on the loose!" "Quick grab some Disaronno!"

And where if your reading this at all your probobly in the lab and Turby is at lunch so you took these sweet minutes to go on Youtube and waist your time that you could be spending doing homework thats due the next class. But instead, your looking up your own fucking school on Urban Dictionary...peanut butter hahahaha
