A beautiful man, inside and out who makes you feel like the most special person in the world. He is very intelligent and thinks about others. He puts the ones he loves before himself and is always up for a good conversation. If you meet a Jack, you will most definitely fall for him!

I didn't mean to fall in love with Jack, he's just amazing!

Jack

A tall, skinny, blonde Caucasian kid with a brain to rival Patrick Starr and Big dick energy to rival Dwayne Johnson. He spends too much time online and never goes outside. Generally nice when you meet him, but gradually becomes more and more of an ass as you get to know him.

Wow Jack this is the fourth time you’ve told me to “Kazoom off a A cliff with a bus full of special ed kids” in 45 minutes. It’s not funny anymore
