Okay, I give up, WTF does IDK mean? I looked it up on Google and it says I Don't Know, but that can't be right?

So far we have:

TMI - too much information
ETA: Edited to add and Estimated time of arrival
ETC: edited to clarify
BFF - Best Friends Forever
WFT - What the Fuck (which actually works for me)
ADA - Americans with Disability Act
LIRR - Long Island Rail Road
DOT - Department of Transportation
WFD - Weaving the Fabric of Diversity
First UU - Unitarian Universalism
RFP - Request for Proposal and Red Frigging Print depending
MTA - Metropolitian Transit Authority
ATM - Automated Teller Machine
LOL - Laugh out loud
BAMF - no idea
WOL - no idea
TNT - I think Turner Network?

I live in a world that is too lazy to spell things out and actually write. Ugh.
We're starting to speak babble people. I need a dictionary for text abbreviations.
