Aggressively hitting on women by force. Often times the "Bull Shark" will be extremely drunk/creepy, and grabbing girls that are not particularlyinterested in them. A patented "Bull Shark" move would be to grab the girl's face and forcibly make out with them.
Labeling somebody a Bull Shark works best while at the beach. Not only is there a "marine life" undertone in its name, but the beach is a prime location to hit on unsuspecting women, allowing you to creep from one bathing suit to the next.
Chris: Dude, look that creeper over there Bullsharking the fuck outta that girl.
Adam: Wow, she wants nothing to dowith him. She keeps walking away from him, but he keeps buying her shots, asking to friend him on facebook.
If your into sea animals, this word is for you. Its likebullshit only with sharks and it can also be used while playing a fun filled sea animal card game.
