Somebody who unnecessarily criticizes somebody, everybody, or a small group of people like an asshole for no reason other than being an annoying ass prick.

Person 1: “Jeremy is such a fucking flakass.”
Person 2: “I know right! One time I was trying write an essay and this mf looks at it in 3 seconds and then pulls out a 5 page lecture about how bad it is before I even started writing it!”
