A common social phenomenon- A 20-something male computer geek with a $1,000 mouse and a bad car who still lives rent-free in his mom's house (attic, basement, or childhood bedroom). Although often of high IQ and with a degree, they are commonly underemployed. This condition is rare among females. Social interaction is limited to people who will come over at midnight.
The sociogeek went into culture shock when his mother threw him out and he got his first electric bill. Sociogeeks are not environmentalists because they never go outside.
