Cockney Rhyming Slang is weird.
[related story: I lived and worked in England for about 4 months. There was a man in the office who would yell dog! when the phone rang. It was explained to me that he was using cockney rhyming slang which made no sense to me because the words didn't rhyme. It took me a while to figure it out.]

Bingo is weird.

And yet Cockney Rhymning Slang for Bingo somehow doesn't seem weird at all.
