Definitions on urbandictionary tagged with 'funny', usually aren't.
I looked up 'aereilly' on urbandictionary today. It sure earned its 'funny' tag.
Used where one normally uses "Pussy" to mean "someone who is weak or cowardly". An intentional misunderstanding of the slang term for comedic effect.
"I am a vagina when it comes to horror movies."
"You're scared of heights? Dude, don't be such a vagina."
