Orignal. Was a word made up from BMX'ers/Skater slang from the early 80s.Today its known as "Orignal Gangsta" which was derived somehow to Ice Cubes silly lyrics just to make a buck because the initials matched lol.

Og stands for over gold. Like when you're wearing too many gold chains.

Did you hear about Fred he died of OG. Over Gold. Like from the movie "i'm Gonna Git You Sucka". A dude dies of over gold, probably the funniest part of the movie.

OG: Someone who registered on OT in either 2000 or 2001 would be called an Original Gangster.

Mike: Wow, you're really an OG?

Bill: Ya rly.

Mike: Can I be an OG too?

Bill: No. OG doesn't mean "Been here a while gangster".
