A common way of rating things. One either places his thumb up to indicate something is good, or okay, or places their thumb down to indicate the thing sucks.

"No Thumbs Down", A definition that will most likely receive a large amount of thumbs down, unless readers reading this decide to double reverse me and add a large amount of thumbs up.
Ex 1: no thumbs down is the dumbest definition on urban dictionary, lemme thumbs up it.

Ex 2: hmm.. hes probably trying some double reverse phsycology or something, so lemme thumbs down this...
