What does the phrase "x-nay" mean?

Question

I hear it all the time, but i don't know what it means

Answer 1

Maybe you mean "ix-nay?" This is pig latin for nix, which means "nothing," generally. I usually hear it when someone is telling someone else to stop doing something, or to put an end to something.

Answer 2

It's like crossing something off. Put an x through it. (Usually, don't say it in present company.)

It comes from Pig Latin, though it doesn't follow that rule. If you were starting to tell someone about Lisa for example, and your friend wanted to stop you he'd say, "Ex-nay on the isa-Lay".
