An act of desparation. In Europe, during the great famines of the middle ages starving individuals would steel the bodies of the recently deceiced. They would hang them upside down over a pot and quelch (form of squeezing) out the half digested reminants of their last meal for their own ingestion.
Im starving, lets go and find a body to quelch.

Get the quelching mug.
An awkward interaction when two people encounter each other in public. Each person attempts to move out of the other's way but move in the same direction, failing to judge the other's direction of movement. The situation can often result in deadlock whereby the only way to extricate oneself is to vocalise an apology and agree on each person's continued route.
Even though the pavement was empty, I still managed to quelch with an old man.

That was an intense quelch. We eventually had to agree that I would go this way, and she would go that way.

A quelch is a vaginal burp similar to a queef. A quelch is common among those that sport gunts and frequently suffer from yeast infections. A wet quelch produces a frothy gelatinous discharge that can be used as substitute for bug repellent. The smell of the quelch ranges between that of rotten rutabagas and orangutan feet. If you encounter a quelch immediately flush all exposed orifices and induce vomiting. Elderly quelchs have been know to cause small dust storms in rural areas.

A cross between queef (a vaginal expulsion of air) and a belch (a loud protrusion of air and often small particles from the mouth). As such, a quelch is a loud belch from the vaginal region often resulting in a light spray emerging from this region.
Hannah quelched all over Rainer's face as he went to fellate her, covering his face in an opaque liquid.
