Arising from a wasted slurring of the two wonderful words "rug muncher", a runcher is someone who devours something with the voracity of a lesbian on heat piling mouth first into pussy.

Related to the mysterious and as yet undefined "duncher"...
"Yo, you are a such a fucking runcher!"
"He runched that down"
