It stands for Heads Up Display. Its a feature of most poker software apps, like Poker Tracker or HoldEm Manager that overlays the stats of the other players at the table as you collect hands on them. It'll tell you things like how many hands they are playing, how often they raise, how often they cbet, fold to a cbet, 3bet, 4bet, fold to 3bet, steal, fold to steal, etc. It helps greatly in making decisions during a hand and you're probably at a big disadvantage if you're playing without one.
