When you can't tell if a female co-worker made a tuna sandwich or sat on the counter
Co-worker 1: did you make a tuna sandwich?
Co-worker 2: No why?
Co-worker 1: Wash out that tuna pouch...

Get the tuna pouch mug.
A slang term or euphemism for "vagina."
Girl 1: Wow, bestie. You really messed her up for saying that about your butt.
Girl 2: Yep. My butt is round, not fat... so I slapped her in the face and kicked her right in the tuna pouch.

Girl 1: That's my BFF! Your butt is perfect, by the way. Let's go get some fuzzy navels.
