A bearicorn is a mammal that is a cross-breed between a bear and a unicorn. It usually consists of a large Grizzly Bear with a horn sprouting in between its eyes. A bearicorn is very vicious and will attack upon sight. The term was coined by Rooster Teeth productions during a gameplay walkthrough of the Rockstar game Red Dead Redemption when the host of the video threw an axe at the bear's face and called it a bearicorn.

A bearicorn with two horns (very rare sighting) is called a double bearicorn and is usually about ten times more vicious than a regular bearicorn. Do not dare to harass a double bearicorn. Although they look harmless, they will kill upon sight faster and quicker than a regular bearicorn. The only way to kill one is with a buffalo rifle to the face.

The bearicorn is a legendary creature that has been described as a bear with a single large, pointed, horn projecting from its forehead. It's a word play for mix of unicorn and bear. It was used by several games and movies.
