The action of someone telling another person that they'll do something in a situation. However, the other person listening to this promise may respond quickly by saying: "Manchest."

This word itself enforces that person who made the promise to literally complete, what they said they'd do.

If they don't complete their promised task to the word, "manchest," the person who said, manchest, may slap the other person in the chest due to their non compliance of their self made promise.

(Manchest does not apply for things someone might do, which they can say to prevent manchest from happening. For example: I ought to, should maybe, might, etc.).
Johnny: I'm gonna get that girl's snap soon, she has some rockin' tits.

Tommy: MANCHEST!

Johnny: Now wait a minute here fucko! I said "soon" that don't apply to my planned action. "Soon" means I'm planning on it, manchest don't count for that dumbass!

Tommy: Oh fine, whatever. . . Hey! What about that girl over there though?

Johnny: My God, I didn't even see her. . . I'm gonna talk to that one for sure then! Wow she's amazing!

Tommy: MANCHEST!

Johnny: ALRIGHT FINE, I'ma head over to her right now then, Tom. Getting slapped in the chest by Tommy, or talking to a gorgeous girl? I think I'ma go with the second one. . .

Tommy: You better do it or you finna get slapped in yo ribs! I'ma watch you! Good ol' manchest!

A "Manchester" is the act of calling a friend or acquaintance on a statement they made. When a person states definitively that they will perform an action, anyone within earshot can call "Manchester!"

After the call, the callee must either perform the act or receive a swift punch in the stomach.

Originated at Rose-Hulman Institute of Technology on BSB 1 in 2008-2009.
Andy: "I'm going to go do jumping jacks naked on the frozen lake!"
Tim: "MANCHESTER."

(At this point, Andy either does jumping jacks naked on a frozen lake, or gets punched.)

A "Manchester" is used in response to an individual claiming a completely ridiculous course of action. Once Manchestered, said individual must complete his claim within 24 hours, otherwise punishable with a vicious open hand slap or kick to the testicles.
