when a male swings his junk between his legs fast enough to produce a "slap" sound. The maneuver is most effective in a North/South fashion. East/West will do, but it's not as loud and hurts your balls.
never do the slap in front of your girl after taking a piss.

It's not a party until a someone does the slap for the ladies.
