Mo

Mo is an abbreviated form of "more," most often used by teenagers. The abbreviation was made popular by rappers like Notorious B.I.G with his song, "Mo Money Mo Problems."

Mo is helpful when texting and chatting online because it shaves off two letters. However, mo and more are both only one syllable when said out loud. So if someone says it he is just trying to sound cool.

An acronym for the Latin phrase meaning "method of operation," which describes a person's method or reason for doing things.
