coined the term

When someone makes up a new word or expression to describe something, and that word or expression is just so sublime and succinct that it is quickly adopted by the mainstream or the sub-mainstream, necessitating its inclusion in the Urban Dictionary.
Beyonce 'coined the term' bootylicious to perfectly describe a rounded butt (or Big Black Ghetto Arse, depending on how you look at it). Well done Beyonce. Sorry I can't do the little dash above the 'e' in your name but Robert's explanations are crap.

Sohm-Yung Ho 'coined the term' Resident Cunt to perfectly describe... um... the resident cunt.

Silicon Dicker

An Urban Dicker is a frequent submitter to the Urban Dictionary. Coined by arguably (ok - VERY arguably) our generation's GREATEST Urban Dicker herself - Emelda Moncelet - who formed a Facebook group of the same name which half-heartedly promises a large novelty penis made of silicon as 1st prize to the most prolific Urban Dicker, though no final competition score-tallying date has every been nominated.

Silicon Dicker is basically an Urban Dicker who submits using their 'construct' (fake Facebook profile), or other alias.
Ivan: "I refuse to give the thumbs up to ANYTHING with 'booka' in the title....bookabullshit."

Ricky: "http://www.urbandictionary.com/author.php?author=Ricky+Foxwell"
