Slappy Hour is the first hour of the night (Midnight, 12 AM) and it goes until 12:59. During that hour of the night, if you hear anyone exclaim that its midnight or simply state the time, you must slap them. This excludes text messages, through the telephone, or anyway that disallows you to physically slap them. You must only slap the slap victim once. Also, no slapbacks.
Robert- "Damn dude, its 12:30!"

Robert- "What the fuck?"
Johnny- "Sorry bro, it's Slappy Hour"
*Johnny slaps Robert*
