2012 will be the year of handheld internet. Messages need to be short and thumb-friendly for typing. Yet we still need to pack in meaningful information along with the core ingredients of courtesy and etiquette.
Hundreds of bizarre jargon expressions have spawned as a result of the modern mobile internet. Primarily about shorthand, modern jargon saves keystrokes to say TY (thank you) and YW (you're welcome). The new jargon also conveys spontaneous emotion and personal expressions ('O RLY', 'FML', 'OMG').
Here is a list of 5 of the more common instant message and text abbreviations.
1. HMU
HMU - Hit Me Up
This acronym is used to say "contact me", "text me", "phone me" or otherwise "reach me to follow up on this". It is a modern shorthand way to invite a person to communicate with you further. e.g. User 1: I could use some advice on buying an iPhone bersus buying an Android phone. e.g. User 2: Hmm, I read a great article on comparing those two exact phones. I have the link somewhere. e.g. User 1: Perfect, HMU! Send that link when you can!
2. WTF
WTF - What the F*ck?
This is a blunt expression of shock and concerned confusion. Somewhat like 'OMG', 'WTF' is used when an alarming event just occurred, or some unexpected and disturbing news was just conveyed.
3. IDC
IDC - I Don't Care
You would use IDC when you are trying to make a decision with your messaging friend, and you are open to multiple options. While IDC is largely an emotion-less term, it can sometimes convey a negative attitude, so it is best to use this expression with friends and not new acquaintances.
e.g. User 1: we can meet at the mall first, then head to the movie in one car, or we all meet in front of the movie ticket box. Wut would you like?
e.g. User 2: IDC, you pick.
4. NVM
NVM - Never Mind
Also: NM - Never Mind
This acronym is used to say "please disregard my last question/comment", commonly because the user found the answer seconds after posting the original question.
Example of NVM usage:
- (User 1): Hey, how do I change my phone to show your photo when you call?
- (User 2): Did you look in the contact list settings?
- (User 1): nvm, I found it! It was on the last screen!
5. WRT
WRT - With Respect to
WRT is used to make a reference to a specific topic under discussion, especially helpful when the conversation is moving in different directions, and the person wants to focus on one portion of the subject.
