A woman who, while normally somewhat attractive, obsessively tans to the point of unattractiveness. The resultant "moldy tangerine" texture of the skin causes repulsion in all men except those most desperate for sex. Members of this category usually travel in packs.
Guy A: Dude, that girl's hot! Check out that booty!
Guy B: Naw man, she's rotten. Look at her orange skin, she's a Crispy Troll. It'd be like having sex with a rotten tangerine.
