vap3;181533 wrotehey so what does the phrase means when he or she is a donkey?
Donkey is a general term meaning bad player. Usually used when someone, who thinks they are a better player than their opponent, loses a pot to that person and utters: "Wow, nice call Donkey". or "You are a complete donkey!". Once and a while used even when someone wins a pot against a bad player, "I can't believed you called that bet, you donkey!"
Also can be combined with the word bet, as in donkbet, meaning stupid bet.
Or shortened to donk, which is usually used in a reflectionary way, as in "what a donk move I just made", or "I'm such a donk", or "I just donked off all my chips".
