ISL

The Independant School League

A league of prep schools in N.E. that basically live to make fun of everyone else...ie, all hate public schools in unity, and then each school hates every other school too...a sad circle of false unity spread by lies and false faces, actuality, a group of individuals with temporary allies and enemies...

Milton Academy, of the ISL, played and smoked Nobles in football again...

isl

An instant messaging acronym meaning "I seriously lol'd."
This came about after lol was becoming over used and needed a more accurate word

ISL

Ugh.... a group of prep-schools in New England, surrounding Boston. Thayer Academy is the only one that remotely resembles an actual highscool.

"ISL football is a joke. Nobles sucks. Milton needs to get that giraffe out of their ass."

Garden Isles

A small waterfront neighborhood located in Pompano Beach, Fl. It is inhabited by GI members, who often enjoy gettin them "thursday seshes". Kids here like to refer to themselves as the GIP, or Garden Isles Posse. They enjoy gettin lifted and fucking shit up around the hood. Looking forward to "Tiki Seshes", inhabitants usually cop large amounts of ganja and other mind altering drugs.

GI usually has the dankest crip in town...

GI has and always will be better than LP.

John-"Them Garden Isles boys be gettin zo0oted"
