The Ichthyosaur from the video game series Half-Life.

It has earned its nickname from Half-Life 1, in which the player encounters it.

During the encounter, some people have said it looks funny, possibly due to its strange expression, erratic movement, and tiny hands compared to the giant mouth.

A catch all word to describe anything that is basic, uncool or untrendy. According to The New York Times, "cheugy (pronounced chew-gee) can be used, broadly, to describe someone who is out of date or trying too hard."

Things that are cheugy:
