Dirty Cherina

The act of getting drunk and going to a student dance party to find a prey for savage snogging on the dancefloor, followed by a not-less-savage quickie in the bushes or dorms.
This act is usually completed with a walk of shame on the dancefloor.

We always knew Sarah was a Dirty Cherina; we saw her get back to the dance party an hour after snogging that random guy.
