The highest possible level of satisfaction with life only to be achieved by young white males who often go to parties, have plenty of money, and slay poon on the reg. You only know you're 'Killin' it' when you're plastered, throwin up the Shaka (surfers' hand gesture), and yelling "I'M KILLINNNN ITTTTT"
Friend: "How yah doin pal?"
Matt: "Don't worry about me man, (shotguns a brew) I'M FUCKIN' KILLINNNN ITTTTT!"
Friend to other Friend: "Hey don't bother Matt, he's Killin' it right now.
Matt: "Don't worry about me man, (shotguns a brew) I'M FUCKIN' KILLINNNN ITTTTT!"
Friend to other Friend: "Hey don't bother Matt, he's Killin' it right now.

Killin is an amazing guy who may come off as mean, but has a very sweet side to him. He'd be willing to lose hours of sleep all for you. He's full of jokes and laughter, and may even love to do stuff like skateboarding. He may not relate to a lot of things but Killin will be there for you no matter what.
