look up any word, like wyd:
 
1.
A girl who rarely moves while doing the nasty. While having sex, one could confuse said party of being a dead possum. This does not include muscle spasms, or other contractions of the like.
Danny: How'd it go with that girl last night, Dave?

Dave: She just laid there like a dead fish.

Danny: That bitch sounds like a possum pussy!
