means talk to me. just an easier way of saying it. kind of like ttyl.

When you eat dirt for the first time and leave your family to build a shack in the woods

T = talk 2 = too M = my S = self T2ms when you dont want to say something out loud. When chating or texting. But you want it to be heard by the other person. If they respond to your little t2ms blurb act as if they are crazy , and you dont know what the hell they are talking about.
