It seems like you're asking about a phrase that sounds like "messieurs force."

However, this is not a standard English phrase. It's possible you meant one of the following:

* "Messieurs" (pronounced "mes-yuh") is the French plural form of "Mr." or "Sir."

* "Force" is an English word meaning strength, power, or compulsion.

If you can provide more context or a complete sentence, I can help you figure out what you meant to say.
