A horny hannah is the embodiment of the female sex drive. A horny hannah is a girl who will always take the guy up stairs to fuck. Even if it is 5 times in the same day. There is no limitation to the annoying hornyness to this girl.
"Pat, did you sleep with that girl amber last night?"

"Naw man. She an annoying horny hannah. I wouldn't dare touch that!"
