A self centered jerk, is very ugly and not a very good person or friend to you. He doesn't think much of others.

Get the Jackmug. 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

Get the Jackmug. 1. "I just got jacked! Someone took my iPod!" or someone got an unfair trade "You got jacked!"
2. "I'm jackin' off."
2. "I'm jackin' off."

Get the jackedmug. The most amazing guy on the planet. Jack makes you feel warm inside. He is short but athletic. He’s attractive when he’s not trying. He will take the time to slow down the conversation and start “small talk” he hits the ball out of the park when it comes to getting girls. They are all over him. He may not be the smartest but he is The cutest!!! He’s my boyfriend!

Get the Jackmug. Dave was really Jacking on today. Not only did he complete all of his work ahead of scheduled, he also helped his coworkers finish their work and he cleaned up the lunchroom.

Get the Jacking onmug. 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!
