Florida High-five 

A high five given to an unsuspecting person after applying baby powder to ones genitals. It is so-named because hotter, more humid areas necessitate such application to prevent chafing, and also because Florida is America's Wang. This is a relatively easy prank to pull, as a hanging hand is so irresistibly inviting and most people accept the invitation of a high-five without a second thought.

(Person X applies baby powder to scrotum with right hand while Person Y is in the bathroom. Person Y exits bathroom.)

Person X: Dude, we're in Florida! (holds up right hand).

Person Y: Hell yeah we are! (grants high-five).

(A faint cloud of white powder encircles the hands, and Person Y realizes he has been given a Florida High-five.)
