The loss of a winning poker hand on the very last card dealt; it is frequently followed by shock, tears, and a severe need to blow things/people up. (Halo, anyone?)
3:36pm All in preflop...equal hands...I hit a better hand on flop and turn and get rivered by my arch nemesis. Anybody with the name of Sandy that you happen to know, go ahead and punch him/her in the face for me. thx...
