lunch dump 

Typically experienced in a public restroom setting everyday between 1:30pm - 3:30pm, whereby the entire washroom facility is inundated by non-courtesy flushers. In this perfect storm, the smell culminates in what can best be described as the equivalent of 1,000 zombies who ate 1,000 tacos, 1,000 years ago, rising from the dead, and eliminating said tacos into the rankest smell ever propagated onto mankind. Global warming is possibly being caused by this daily activity.

Hey Jesse, avoid the men's room for the next hour, Jimmy and co. just got back from Wingin' It and are engaged in the daily lunch dump. I literally held my breath the entire time I was in there to keep from bleeding from my nose and mouth. All I want for Xmas is a courtesy flush from those fuckers.

dump lunch 

Dump lunch- v. To vomit profusely and noisily due to sickness or reaction to disgust.

The smell of the formaldehyde and the sight of frog guts in biology gave me an almost irresistable urge to dump lunch all over the dissecting table.
