look up any word:
1. 1 thumb down
when someone has no thumbs up and 1 thumb down. pathetic enough to have a thumb down, but not noticed enough to have multiple thumbs down. aka the epitome of self pwnage multiplied by everyone who overuses lol.
someone who has 1 thumb down racks up so many nub points that they are court ordered to have their testicles removed

they also vaporize in the presence of Chuck Norris
