Piss and tell

An informal and more discreet way of conveying the use of a pregnancy test kit.

Girl, you don't have to keep worrying if you're pregnant or not- just go piss and tell!

Piss and Tell

The act of boasting to friends about an abnormally lengthy urination, commonly precipitated by over-drinking alcohol or water.

"Woah guys, did you hear that? I was going for like a minute and a half"
"Sit down Jake, you dick - no need to piss and tell".
