An extremely stinky bathroom- one that smells like an overflowing septic tank is right underneath it. Meth labs generally have several stalls, each of which is equally noxious.
I'll be right back I have to go make a deposit in the methane lab.
The meth lab in the videotpae department where I work smells like its overflowing with 60 years of shit.
