look up any word, like tribbing:
I can define 'humpbump', but Urban Dictionary would refuse to publish it for no adequately explained reason. Again.

Apparently, correct spelling, acceptable grammar and a modicum of wit generally fails to "make the cut".

And yes, I have viewed extensive UD entries to gauge what material might be considered acceptable. Given the overall level of scholarship displayed in this *outstanding* specimen of vernacular lexicography, I suspect that any further submissions may need to be made using human faeces smeared on a tattered brown paper bag.

Thank you, and good-night. :p
