¡No manches!

¡No manches! is Mexican Spanish for “no way!”, “you're kidding!” or “come on!”. People say it to surprising news, good or bad, and to someone who's asking too much. Literally it means “don't stain”. It's the polite cousin of a much ruder Mexican expression, so it's safe with friends, but keep it out of the office.

Register and sound
Register. Informal, among friends. Clean enough for family, too casual for a job interview. Mexicans soften it further with ¡no manches, qué bien! for good news.
Sounds like. no-MAHN-chess. Stress on MAN; the ch is the same as English “church”.
Questions people ask
Is no manches a bad word?
No, it's the clean version. It's informal, and it replaces a ruder Mexican phrase, which is why some parents frown at it. Among friends it's completely normal.
What does no manches, güey mean?
“No way, dude!”. Güey is Mexican slang for “dude” or “mate”: friendly among friends, rude with strangers.
What can I say instead of no manches?
¡No me digas! (“you don't say!”) or ¡no puede ser! (“it can't be!”). Both are neutral and work in every country.
