The adversarial GM-vs-Players GM, where everything you try doesn't work. All things are set at absurd DCs, all monsters are unhitable an always make their saves but hit you everytime, all riddles are unsolveable (except by NPCs), and all rulings go against the players.
The nondescriptive GM, where either all characters are going blind or are wandering around in some dense fog. Never describes anything. All combats start at a distance of no greater than 15 ft. You fail to notice visible huge ancient red dragons at 30ft.
The tax audit GM. You have to keep track of every little item, arrow, spell component, scrap of paper, meal or ration, piece of dirt. You spend hours calculating and recalculating encumbrance, movement, which spells you can cast, how much damage all of your items have taken, how long it's been since you slept, spell durations, ate etc. They insist on going over your sheet before and after the game to make sure you aren't wrong. Next nailing you on encumbrance, they suddenly demand the kitchen sink in the middle of the dungeon. What do you mean you don't have 100 pitons to climb this cliff.
