Thumbs Down

When talking about the Urban Dictionary ratings system, the opposite of the thumbs up. Where a thumbs up denotes a good definition and thumbs down denotes a bad one. There aren't many definitions out there whcih don't have at least one thumbs down. Whether or not people actually like a definition, they will give it a thumbs down, because they hate everybody, the world is unfair to them and they like to cut themselves.

Only assholes give definitions the thumbs down, unless it really sucks.

thumbed crusader

The slang term for a person who forays into the backdoor of wanton vixens, with the goal of altering the pigmentation of his thumb, because he is too cheap to enlist the services of a tanning salon.
Usually repeats the action until the desired shade of brown/tan is obtained. Will also giggle gleefully once successful.

"The thumbed crusader pursued her ass with great vigour, an image of perfect thumb brownness at the forefront of his mind..."
