Get the Billy Bookcasingmug. 
Billy is one who is intelligent but uses it only for his personal uses, which are usually horrific. He’s an incredible liar and doesn’t trust in people, but can feel affectionate feelings over time. It’s safe to say Billys are neither good or bad, they’re just a bit of both.
BILLY!!!!, I cant believe he lied to us, he deceived us, he betrayed us he’s always 1 step ahead, I’m not sure I can fight him”
