a term "created" by the character guido carosella (AKA 'strong guy') from the Marvel comic book X-factor in the 1990s. It denotes a self-absorbed person that is ignorant of the world around him but is not a "stupid-head."
"guido, is that guy a blork?"
"him? nah, he's a stupid-head, blorks are much more self-absorbed. remind me to hit him later."
a character mentioned on homestarrunner.com that has never actually appeared. apparently he moved away after the fifth grade.
Homestar Runner mistook Strong Sad for Dripping Yellow Madness whilst wearing cool shades covered in yella (yellow) paint.
