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.

When some little bitchboy is acting like a little tiny pee pee poo poo baby and messing up the group plans.

Used to describe a very chubby fish, most commonly an inflated puffer fish. A good example is the January meme of 2020 with the puffer fish eating a carrot meme.
