A guy who is caring and sporty. He can make you laugh, is extremely kind and probably gorgeous. He is a lot of fun to hang out with and is very original, creative and can entertain you endlessly.
If you ever get hold of a Bart: never let him go, you'll regret it.
"Damn, I turned that guy down, he asked me to prom with him."
-"What?! But he's definitely a Bart!"
Get the Bart mug.
