An aura of attractiveness that people with a disability or handicap have.

Come from the anime Code Geass in which Nunnally is a very pretty blind girl in a wheelchair.
Person one: How can you think that girl is hot? She's in a wheelchair for god's sake.

Person two: I don't know man. She's got the Nunnally factor.
