Slang for the break room of an office. Called this because when a cake, cookies or other
goodies are left out, the office workers tear into it like a
Piranha on
fresh meat.
Sally: Are those
girl scout cookies?
Betty: Yes, I bought them from
the neighbor girl.
Sally: Don't leave them in the Piranha Tank or you will never see them again.
Cristi left her day old donuts out on the table in the Piranha Tank and they did not last til noon.
