A man who tells everyone his cock is small, but in reality, he's really just saying that so that when his cock is revealed to those who finally have sexual relations with him, they would be suprised by the girth and length that it actually has.
"I made love to him last night....he's a Jalu you know!"
Used to describe someone that is really dumb and laughs at his own jokes. He wears Aeropostle and Hollister clothing. Most likely drives a sports car, preferably a baby blue Mustang. Usually laughed at by others. Also has tons of cats.
