I'll go first.

One time in Bangkok after a 1.5 hour thai massage, I heard the lady attendant telling me -

P3nis, p3nis!

I was a little surprised but realizing I was in Bangkok I got a little naughty but thought better of it and told the girl - no, no, I'm good. But she insisted and pull my shoulder -

P3nis, p3nis!!!

Then I realized she meant Finished!

I was a bit embarassed so I got up and gave her a tip and went out to settle the bills.
