Word invented by the social fraternity Delta Tau Delta, meaning a PaRtY-Tornado. These can be seen the next morning after a long night of partying. Beer cans scattered about the house, broken furniture, walls, and feelings.
We partied so hard a Parnado came through here.

We're heading to shitty city and, I hear a Parnado is coming!
