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's are beautiful guys, inside and out! Usually tall with blonde hair that you want to run your fingers through, and their eyes, don't even get me started! The most beautiful blue eyes that sparkle when they laugh. If you happen to be friends with a Jack, I'm so sorry, cause chances are you have a MASSIVE crush on him. He is the full package and he doesn't even know it, and if you somehow manage to get into a relationship with a Jack then you better thank the heavens and keep a tight hold on him.
Girl 1: "Omg I spoke to Jack today and I couldn't stop staring into his eyes!"

Girl 2: "Wait don't you have a boyfriend?"

Girl 1: "Yeah I do, but this is JACK!!!"

Girl 2: "True, you go girl!"
