Jack is one of the hottest boys you'll ever meet, he's smart and has the best personality, although he might come off as a bad boy, he is so funny and amazing and I'm so lucky to have him in my life.
Friend: wow! Who's that

Me: oh that's jack, I'm so glad to have him in my life

Friend: aw you're so lucky

Jack

A 100% undesireable douchebag that will break your heart. Never trustworthy. Always looking for another girl to cheat on you with. Lies a lot. Criticizes you to no end.

Jacks usually have feelings for a person but they are too shy to tell them. The people they like probably like somebody else but they don't care. He is smart, funny, awesome, handsome, and doesn't care about what other people say about him. If you know a Jack you are one lucky person to be his friend! :)
