A not-so-affectionate nickname for New York Yankees third baseman Alex Rodriguez, coined by Boston Red Sox fans during the 2004 playoffs. "Slappy" refers to his act of slapping the ball from the glove of Red Sox pitcher Bronson Arroyo, who was trying to tag him. Rodriguez was called out by umpires for this bush-league move. The latter word refers to A-Rod's lips, which for some unknown reason retain a purplish-blue hue as if he just chugged a gallon of grape juice.

To be jerked off while sleeping as a revenge attack for being a total piece of shit. Usually the discharge is aimed at the stomach of the victim to make a messy aftermath. When the victim wakes up they will see the cum on their stomach and realized they had been slappied but don't know by who, hence it being a Ghost Slappy. This is in no way gay.
Friend comes home really drunk, pukes on your floor and passes out.

He wakes up and says "Fuck I got Ghost Slappied again!"

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.
