I've been seeing this at Doyle's Room lately. I tried it out for Play Money and it was sort of interesting, but I also have no idea as to the actual strategy of the game. I guess it's a 4-card lowball game with pairs and cards of the same suit counting against you. If you manage to get 4 cards of different values and different suits, that's a "Badugi" hand. Good luck if you do decide to try it out.
