A player or fan of lacrosse. Usually wears all colors (mostly bright...doesn't have to match) of high crew socks, old school (but fresh) kicks, ridiculous designs on gym/lacrosse shorts (with pockets), and has long hair. One can find other lax brahs wearing polos with popped collars, sandals, shorts (no cargo) above the knees, and a golf hat with some sort of lacrosse logo or school on it...again with outragious colors. <--mostly adult brahs
"Hey I'm down in Balitmore for the Memorial Day weekend championships...you should see all these lax brahs!"
