A pokergame in which all of the players are terrible, make stupid bets, calls, etc. No skilled required to play, just pure dumb luck because the players are so clueless.
I went to Sherri's the other night for a poker tournament, but it was a complete donkfest!
A donktress is a woman that carry's behind her a large rear end like that of a female donkey. It is a common used term among the Mexican peoples of the Yucatán peninsula.
HeyPedro, take a look at the lady over there, see how much she is carrying in her ass, she is a donktress.
