Hot Garbage

Hot garbage (also known as hot garbo or simply garbo) is a term used to describe levels that tend to get spammy and are not that much fun to play, despite being packed with trolls. They more commonly contain spaghetti solutions than puzzles with funny deaths, and the majority of Mario Maker levels are like this, making it difficult to find a fun level.

Hot Garbage Techniques
The first obvious thing present in garbo levels is the overuse of enemies, especially Hammer Bros., Magikoopas, and Bowsers. There is usually a dev exit that involves hitting a hidden block to the very left of the level that contains a Star.

Another thing commonly present in these levels is pick-a-path, with no clue as to which path is correct. Decisions in a level should follow the 50-50-90 rule, not simply being a 50-50 chance.

Yet another common thing is the spam of kaizo blocks over pits, and repeated kaizo tricks being necessary. This all just cooks more spaghetti for the player.
