When you are playing Tetris and have a mild-to-major case of Tourette's Syndrome, or involuntary spurting of cuss words, grunts, miscellaneous sound effects, etc. Usually due to a stupid keying mistake.
I was quick-dropping some sick Tetrises and Tetris pieces in general, but I accidentally pressed spacebar (quickdrop) instead of rotating the "t" piece once more... I once again went "quick-drop crazy"] and wasn't accurate enough to land a tall piece in the appropriate whole. This led to a bad case of Tet-Tourette's, because my impeccable design to clear lines like crazy was ruined.
