Run the Bull

Doing a girl from behind while making snort noises like a bull, and pointing your fingers in front of her head to look like horns.

Dude, I hooked up with this crazy chick last night. She was on all fours, so naturally I assumed she wanted me to Run the Bull.

go full bull

Just rage, go absolutely apeshit. Shake face angry, ready to roll heads.

I thought for a minute someone stole my Xbox and I was about to go full bull.
