Pac-Man

Etymology
From the popular arcade game  (1980) and its player character, a circle with a snapping mouth gobbling dots in a maze. The original Japanese title of Puck Man was derived from the Japanese phrase “Paku paku taberu” which refers to gobbling something up; the title was changed for the North American release to mitigate vandalism.

Noun
