Buffaby
The enormous crap you take after eating entirely too much food at a buffet (typically chinese or mexican food). The crap is usually accompanied by a large amount of gas, splattering, & an odor that would gag a maggot. It is not typically in solid form due to the rushed manner in which it is delivered.
That buffet almost killed me. I just went and had a buffaby in the men's room. I barely made it 30 minutes. I would avoid that area of the building at all costs.
