Spencer 

A COMPLETE douchebag, he will stab you in the back. He'll cheat on you with 2 other girls (one of them your best friend), make you feel like the only girl on the planet, build you up, then knock you down, stomp on your heart, and stab it with a spoon. DO NOT DATE A SPENCER

"Wow that guys such a fucking asshole,"
"God, I know, he's such a spencer."
