The act of "careering." Once a great achievement is made it is usually followed by the yelling of "reered." May be stretched out for emphasis. Can be used as a verb or adjective.
"Last night was awesome, I don't remember shit."
"Great fuckin tits babe"
- " Yeah she's completly reering it right now"
- " She's a slut to."
- " That's reered for you."
