A certain species of blowfish found in only suburban counties. Usually seen eating or playing a gameboy, he is very vulnerable to occassional slaps across the face. Isolated most of the times, he takes no interest in sports, the only time when he can be found in public is when he is hanging around summer school.
Damn, that thwart's been on the TV for a longass time. Kick his ass and get him off.
