Similar to tldr. Literally means "too gay; don't care". Used primarily on internet forums by trolls. It is usually written as a one-line response in an effort to satirize the thread in which it is written. It is also meant to be insulting to the initial poster by informing him that he has written something stupid and uninteresting. However many trolls will use "tgdc" regardless of the content of the post for the sake of being irritating.
"OMG Wubsy and Supdudeslol are sooo annoying!! All they do is troll the Dethecus forums the entire day!! We can't have any real discussion! This makes me really angry since the forum is all I have in my life!!
