A person so full of luck in poker that it is disgusting and ridiculous. There is surely some skill involved, but a luckbox will demonstrate more luck mixed in with that skill than any other player.....ever......in the history of the world......even more than Chris Moneymaker, which is just absurd.
Player 1: I just caught a flush on the river to win a 500 dollar pot! The other guy had Aces but I cracked them good!
Player 2: Stfu you luckbox.
What a dumbass poker player, who only plays strong hands and almost systematically all-in, calls a gambler, who sometimes calls with speculative hands and a higher stack, when the latter wins the pot.
NL Omaha 8 tournament, final table, blinds 25-50
Gambler (3000$): 4567 limps in
Tight player (1000$): A99K calls the SB
Flop: A 2 9
Tight player (with a set of nines and no low) shoves 500$
Gambler thinks for a minute and then raises all in (with a good LO draw and two straight draws)
Tight player calls immediately
Board: A 2 9 5 8
Gambler scoops the pot: HI 56789, LO 65421
Tight player writes: "you fucking luckbox"
