sharkchalk 

Liquid chalk. A liquid version of the traditional block chalk that has been used to improve grip in weightlifting, climbing, and other sports that require grip strength.

The name derives from the texture of actual shark skin. Shark skin will allow a hand to move freely in one direction while halting the hand if it were to move in the opposite direction. Liquid chalk or sharkchalk goes on smooth, then grips.

Do you use block chalk or have you upgraded to sharkchalk yet?

SharkHawk 

A SharkHawk is a modern haircut that combines two other more popular men's do's. The hair is spiked in the front but there is a "tail" coming out of the spike in the form of the front half of a fauxhawk.

"I can't decide if guys with SharkHawks look like douches, or sexy as hell."

sharkhack 

collegial term for the verbal and non-verbal cues that an experienced litigator or trial lawyer uses to command presence in a court room, convey trust with court staff, increase efficiency in the administration of justice, and/or displaying an ethical manner in representing issues before a judge.

That lawyer used a real sharkhack, to tell the judge he needed more time.
