A version of m8 spelled incorrectly, sometimes on purpose as a joke. m8 (m-eight), short for mate is often used in in-game chat on consoles and PC to be as efficient as possible when communicating.
Mountain-Dew fueled and sleep deprived, childish gamers sometimes lose all ability to type correctly when raging and type m9 instead of m8. An unavoidable typo when blinded by rage because 8 and 9 are next to each other.

when some one is even better than a mate. can also be used for great, gr9, hate, h9, etc.
the value decreases or increases depending on how much the word applies to the situation, eg, gr7 would mean something not too great
person1: hey i brought food
person2: m9

When a newb tries to be a smart arse when calling you mate abbreviated as m9 instead of m8 just to piss you off. More commonly when playing an FPS such as Battlefield or CoD.

Usually the modern day word for 'mate' has been abbreviated to the simpler term of 'm8'; read as 'meight'. As you know the number 9>8 therefore we have the conclusion that m9 is better than m8.
Pronounced 'mnine'.

Commonly thought of as mistakes on messenger services, however the terms are both equivalent to M8 - obviously an abbrieviation of the word "mate".
