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.

Get the Luckbox mug.
Someone who has absolutely no skills in poker, plays like a fish but gets there every time, someone you love and hate at the same time at a poker table.

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"
