Power Pills are the large
blobs in the corner of the screens of a game of
Pac-man. When Pac-man (or any member of his family) eats one of these, he goes
OTT and starts chasing after the flashing ghosts. These ghosts are Pac-man's enemies, and usually chase him: but when he eats a power pill he becomes
supercharged and can chase and eat them.
Of course, these pills have been
associated with the
drugs culture of the 90s, and the idea of Pacman taking pills on a regular basis was probably a
Bad Thing.
They've also been insinuated in
how Pac-Man and Mrs Pac-Man have sex
