A (negative) label for people who are boring, typically used by the LGBTQ+ community to point out people they don't like. Though, it really wouldn't make sense to use it if you yourself are, indeed, straight. Unless you have decided to come to terms with the truth, of course.
1.(adj.) A derogatory term used by homosexuals to counteract the incredibly annoying "that's so gay" / "you're such a fag" phenomenon.
2.(adj.) Heterosexual.
