Ice-T is known for being mad at the internet, and being mad at law and order. You might know Ice-T from his role on Law and Order. When someone calls you an "Ice T," it is a way of telling you that you can't handle the banter, and act like a Tipper Goreknock-off.
My friend and I were playing Call of Duty, but he started getting so angry at people making fun of his lack of skill that he ended up rage quitting, and crying in the bathroom. It was just like the Ice-T video played at e3, except my friend isn't an old woman.
Ice T Tha Realest nigga in the game, with his big mansion, White blond bitch with double D implants, and hardcore rock band that said Copkiller with no remorse, before changing the tracklist and making the song virtually disappear from the earth until The Internet existed, and eventually getting the role of a cop on Law and Order SVU.
Still despite all this he's never been called one by any notable source. This might be do to the fact he is the most hardcore rapper or the fact he can go 60-0 on Call of Duty Modern Warfare 2.
