Omaha is a flop game similar to hold'em, but with two key differences. First, each player is dealt four cards instead of just two. Second, a hand must be made using exactly two pocket cards (out of those four) and three from the table. That is, if four suited cards hit the table, you still need two more to make a flush. And if you start with four aces, then you have a pair of aces, with little chance to improve. The high-low variant of omaha, with an 8 or better qualifier for low, is especially popular.
The term "Omaha8" is simply shorthand for omaha high-low split, with an 8 or better qualifier for low, is especially popular.
