The most pathetic response anyone can give you during a text or instant message conversation.

Mostly used by immature girls that don't actually give a fuck about what you're doing...especially if they couldn't even type out something longer then a 3 letter response.

2nd in pathetic to "lol", people that use "nmu" in a serious form deserve to be forever deprived from their cell phones and computers.

If a response as pathetic as "nmu" is used as a response, you should not even respond in the first place.

It’s an acronym standing for Can’t Remember A Fucking Thing. It’s usually used to describe embarrassment at being unable to remember someone (CRAFT moment); going onstage as the lead in the latest theatrical performance and your mind goes completely blank (CRAFT situation); the next morning after a night when you got pissed as a fart and woke up in bed cuddling a traffic cone and a string of fairy lights wound round your prick.

not much, you
also: nm e - nothing much either

Online lingo; abbreviation for "Not much, you?"

Originating from the phrase "nm u" in response to asking a question similar to "What's up?", an NMU is a person who seriously does not give a flying fuck about what you have to say. These people often seem uninterested over text, and would rather be doing whatever they are doing. They are the apotheosis of not giving a shit. NMU's often use terms such as 'same', 'wow!!', and 'cool' etc. Use 'lol' to compensate for the complete 'I don't give a shit' in their soul. Occasionally will use sarcastic exclamation marks. Never uses capitalized letters, unless screaming.

The emu's more popular and successful cousin; commonly used in AIM slang.
