An evil genius who has tried to kill; Bart Simpson; Selma Bouviere; Krusty the Klown (x2) and probably others. He has also attempted to blow up Springfield, but mended his ways twice, thrwarting his brothers plans to flood Springfield and helping homer find the man who was trying to kill him (Frank Grimes' son).

Sideshow Bob bears a grudge against the world.

Named after the Simpsons character due to the resemblance to his hair, this is when a cigarette is rolled and the finished product has an excess afro of tobacco poking out of the top.

Sideshow Bob existed before the Simpsons, the expression is a generic term for any insignificant person. More likely to be used by a cheeky mate or a toxic friend rather than an enemy.

Who's that loser she's going out with, some sideshow Bob, no idea.

Sideshow Bob 

An evil genuis. Captain chaos and the penguin are nowhere near as intelligent.

Sideshow Bob will never throw a beehive at Bart. It's beneath him. He'll do something even better.
