"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...
1. A condition which afflicts some Urban Dictionary entries; an 'up' option may appear, but there may not be anywhere to click to show one's detest of the entry. Usually a problem with one's browser or internet settings
2. Something so goddamned awesome that it can't receive a thumbs down rating. Not even thumbs down trolls can touch it.
3. See 2., except it's not really awesome, someone has just been flooding the thumbs up section to hyper-inflate the quality of the item, or the webpage is so subjective to a certain class of viewers that it has no on-site relativity
