GG, NH, NC, TY, GL, etc!
If you play online poker, you will see all of these acronyms that are common in every country, no matter what language you speak. An online discussion could look like this: - Wow, NC, NH! - TY! GG! - GG! GL! Translation: One player wanted to bluff another. The player called the all-in bet on the river with a single pair. The player is surprised and expresses to the other player that he is surprised and finds his call bold. "Wow, nice call, nice hand!" TY means "thank you" and both players conclude with a GG, "Good Game", GL (Good Luck).
