People who don't look at explosions, as defined in The Lonely Island's song Cool Guys Don't Look At Explosions.
Cool guys don't look at explosions; they blow things up and then walk away. Who's got time to watch an explosion? There's got cool guys errands that they have to walk to.

A poser, loser, wanna-be, f'tard who thinks they're being oh so cool on their new motorcycle or in their brand new mustang. they have "badass" hairstyles, and make loud noise when the situation doesn't call for it. they need attention and hope they'll get lucky with any girl that gives them a look of disgust. when you say cool-guy, you need to emphasize the double o's in the word. It ends up sounding like "coo-guy" but with a faint "L" at the end and make it sound really sarcastic. I don't fuckin care that you have a brand new Ducati, brand new Oakleys, and a "sexy" mohawk, you're only 15 years old you dumbass! You're not cool!

Kid 2: Fo sho, wish i was a Cool-Guy...what a loser

Noun; a guy who is well-liked and pretty neat. Often is interesting and tells funny jokes, and is usually successful. A cool guy will most likely be in charge of many groups and activities. Just a pretty quality person.

Christian: Yeah, he's a cool guy.

A douchebag who frequently posts on urban dictionary.
He practices douchebaggery in every post and ultimately fails in every sentence. His "diss" on blink-182 for example was cleverly titled "Blink 180". Probably in the age range of 1-11 and with the musical and mental capabilities of a goat. He cant even spell and enjoys eating his disgusting little abused features when he's home alone :)
Coolguy on "Blink 180": "worst band ever, it is so crapy I whant to eat my ears when I hear it
almost as bad as u2, greenday, and all thos crapy emo bands"

'Nuff said.
