Badoggie: a badugi topped by K-9, such as K954. As the name suggests, it's a bit of a dog.
Badugiflation: a phenomenon in which your opponents are showing down huge hands, i.e. fours and fives, left right and centre. Your sixes and sevens, which were bloody good hands back in the day, just don't cut it any more.
1. A really rough jack badugi, like JT85, as opposed to a smooth jack.
2. Absolutely nothing.
Thus if you're sitting on a king or queen badugi in a live game and your opponent proclaims he's got "jack shit", you're none the wiser.
Knuts: the worst possible badugi, namely KQJT. Either play it fast or dump it, depending on your position and your opponents. Pronunciation of the 'k' in 'knuts' is optional. Appropriately for this hand, "knuts" backwards is "stunk".
Monstered: we've all been there, and if you haven't, you soon will be. When your virtually unbeatable hand gets beaten, you've been monstered.
Number two: normally number twos stink, but not in badugi where the term refers to 532A, the second-best hand in the game. Losing with this hand (it can and does happen!) requires the ultimate monstering.
1. An eight badugi. The word is used similarly in golf to refer to an eight on a particular hole.
2. Someone who likes to pat-bluff, or snow, a lot. Snowmen are tricky customers.
Ugi: a badugi which isn't bad, such as an eight or nine. You'll often end up calling off multiple bets in a big pot with your ugi, in the vain hope that it'll somehow be good.
So there you have it. Best of luck at the badugi tables and may all your pat snowmen hold up.
