Megatron

A crazy ass bitch who will stop at nothing to get fucked up. A good friend, but also a good friend who is always willing to fuck some shit up. The girl who gets high before night class and brings fruit loops. The girl who almost quit lacrosse to go on spring break, because she wanted to fuck shit up so badly.

"Did you tron last night?"
"Oh shit, Megatron was out last night"
