Sexy-ugly

A person generally not considered to be attractive by many, but who is hot as fuck.

Examples: Shia LaBeouf, Malcolm McDowell in 1971 A Clockwork Orange,

Girl 1: Hey I’m not gonna need a ride from you later, I’m going home with Mike.
Girl 2: How much have you had to drink?
Girl 1: No it’s not that. He really turns me on.
Girl 2: Really?
Girl 1: Yeah, I think he’s sexy-ugly and it’s gonna be hot as hell!
Girl 2: Ok, I can kinda see it. Have fun!
