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.

I just hit my thumb with a hammer today. This hammer thumb makes me feel like an clutz.

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.
