Slap Dick is a commonly played game where two guys get hard and sit facing one another. They then proceed to switch off slapping each other's dick. The guy whose dick falls off first is the loser. Following the game, the winner may choose to do the victory ritual: pick up the fallen off dick (before it looses to much blood and becomes limp), smack the loser's forehead with said dick and finish by yelling SLAP DICK!

December is the month where you apply your hands in a slapping action to any penis (male or female) you may encounter.
Terry: “do you have a dick”
Todd: “yeah?”
Terry: *slaps Todd’s dick*
Todd: “Why’d you do that?”
Terry: “It’s slap dick December”
Todd: “yeah?”
Terry: *slaps Todd’s dick*
Todd: “Why’d you do that?”
Terry: “It’s slap dick December”

when you hook up with a girl that should not be present in broad daylight. The term comes from the fact that you'd have been better off slapping your dick against a wall for some form of pleasure than putting it anywhere near that creature's hatchet wound.
Dude I can't believe you banged that skank last night...should've just slapped your dick against the wall..
