Poker Acronyms - OMG
OMG= "Oh My God"
Usually used at online poker tables - "OMG" or "OMG!!" is often typed in response to a seemingly unbelieveable development on the board - e.g. a player making a straight flush, or a player who was miles ahead before a flop suddenly becoming a dog after the flop.
Note : after playing online for a few months, you will probably stop typing OMG because you will have seen everything, and nothing will cause you even the slightest surprise.
