Poker Acronyms - GL
GL= "Good luck"
Usually used when at an online poker table - often typed by a player at the start of a poker tournament (sometimes written as "gl all" or "gl every1" - the latter meaning "good luck everyone"). Also typed when a player or players are all in, and awaiting the flop, turn or river.
Note : nobody at a poker table really wants their opponents to have gl / good luck.
