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!

slap dick- one for whom even the simplest task represents a monumental challenge. One who is forced to re-learn all tasks on a daily basis due to exceedingly low intellect.
When Evan confessed he accidently scalded himself in the shower every morning he was instantly recognized as a total slap dick.
