In poker, a Douche Bet is when a
player bets the exact amount of
money another
player is holding in order to intimidate that specific player instead of just betting.
Because a Douche Bet is a very specific bet it usually takes additional time to count the opposing players chips and then counting out their own, waisting everyones time at the table.
If any player caught playing a Douche Bet all other players should state, "Douche Bet!". And for the rest of the night the player is now known as "Douche at the Table"
