A militant geek who was maliciously and relentlessly teased in high school who later goes on to discover the internet, and takes out his self esteem issues on random unsuspecting online community members. He often tries to mask his many shortcomings by masquerading as someone of superior intellect. He is seen as unattractive and sub-par by females, which almost guarantees he will be the first to invent a sexually fuctional computerized mate.
Honey, Junior has been getting picked on a lot in school lately, I'm worried he'll become a Thad.

He's 38 and unmarried? What a Thad.

Another term for the "Yawn-And-Put-The-Arm-Over-The-Shoulder" move all guys have done in the movies at least once. Quite cheesy, yet on the other hand takes alot of effort into doing it just right.
Guy: *Yawns and puts arm around his girlfriend during a movie*
Girl: Babe...
Guy: Yeah?
Girl: ......You just pulled a Thad.

Elderly Woman: Youth these days...Pulling Thads all over the place!
