Someone who is
short tempered, frequently asserts themselves over others, and wrongly accuses
people for things they didn't do. They are usually a complete
asshole as well.
Joe: "Did you hear about what

Tom: "Yeah, he took control of the Soup Kitchen, claimed himself as King of the Homeless, and then accused the lead chef of murdering his
cat."
Joe: "Yeah, he's a Captain
Skinny-Dick"
