What is Brocus Pocus?
1.
When a girl is being hit on by a "bro" (lifted truck driving, moto-cross riding, hurley apparrel doning guy with spiky hair and possible frosted tips) and she declines the attention... but by the end of the night and a few drinks later, she realized he had tricked her into a make out session of some sort.
"I didn't even like that Jared guy. I think he sprinkled some of that brocus pocus on me and i ended up kissing him."
"We're on our way to the Avenged Sevenfold show, so make sure no bros sprinkle you with brocus pocus."

The act of a male fingering his own asshole during masterbation or otherwise.
