I tend to call "donk bets" any bet into the player who showed aggression on the previous street. I am not sure if this is true, but I was told we call it like that because the player (donkey) often does not acknowledge the strength that the aggressor showed on the previous street. By doing this, he is being as stuborn as a donkey. Makes sense, no?

I also call donk bets, the river bet at the end of a wa/wb line, and a turn bet for a stop n go.

I think the term is more appropriate for limit hold'em, since in this game, value betting and keeping the lead is much more automatic. So check raising the player who showed strength on the previous street becomes a routine play as it allows to get more money in the pot.
