Oldschool 

Retro. Simple as that.

Oldschool is one of the worst slang terms ever invented. Only retards use that "word". Almost as bad as the word hardcore.

Seriously....when anybody uses the word oldschool they sound like a fucking mongoloid.

Oldschool is a terrible word. Say retro instead.

I happen to be a moron so i use the word oldschool extensively.

Oldschool 

When your word was your bond, if you play you're ready to pay (you don't rat out anybody) or "drop a dime" to avoid taking responsibility for what you did. "Drop a dime" refers to making a call from a public telephone. This was before even pagers...

"No worries dude, you can trust them, they're oldschool.'
