Chatroom Online Midlife Crisis (COMC)  

Someone, middle aged, who changes their blog/chat/screen/etc... names, for no other reason other than, they are suffering Midlife Crisis, offline, which has spilled into their online world. I was studying this, AND, knowing this guy from chatting with him for years, I have determined (and coined a new phrase in doing so,) that dude is suffering from COMC (Chatroom Online Midlife Crisis.)

Just now, I was chatting in the room with someone I have spoken to for about 4-5 years, who is pretty much a f'ing jerk, and someone was asking him why did he change his screen name, again (since he didn't lose it to terms of service violations.) I was studying this, AND, knowing this guy from chatting with him for years, I have determined (and coined a new phrase in doing so,) that dude is suffering from Chatroom Online Midlife Crisis (COMC)
