It's not just uppercase lower case, it's butchered spellings of words to make them as difficult as possible to read.

A derogatory name for the military haircut know as the "high and Tight". Since the haircut is very conservative it makes the wearer look like a complete turd, hence the name turd cap.
Did you see Private Barton, he just got his turd cap touched up. I guess they forgot tell him they have the technology to fad your hair these days.

Dumbass way of typing that makes you look like you don't know shit about computers and are just randomly pressing the shift key. Usually combined with bad spelling (ie, lyke, wut, dat, h0lla)
