Trout Buffer 

A term used to refer to a person's mouth. Typically used in circumstances such as "shut your whore mouth" or "shut your pudding hole" whilst evoking confusion but also intrigue in the recipient. Derived from the pseudonym for a penis (popularized by the phrase 'drop trout') combined with the polishing ability of saliva and motion of the tongue and lips in a manner similar to buffing whilst performing oral sex.
