A young person, usually between the ages of 12 and 15, that thinks they are alot older/cooler than they actually are. Often can be found at the mall or movie theater on a friday night in groups of 5-10.
How to spot a jit...
girls- seen wearing too much makeup, clothes that do not fit correctly, and a fake designer purse
boys- often a foot or so shorter than the girl, seen wearing the most "ganster" clothes possible even though they are often rich young white kids
I counted at least 20 jits as I was walking through Town Center Mall today.
Man! This place used to be so fun to hang out at...not it's overrun by gits!
