look up any word, like pussy:
usually referred to as "that guy" at a party or anywhere for that matter who just can't seem to say or do anything remotely intellectual or worth-while..
John: "hey baby, do have a mirror in your pocket?"

Betty: "what a slap-dick, get lost."

A game where two or more men put honey or other adhesives on their hands and take turns slapping each other's wangs.

The game goes on until someone's hand gets stuck on another's penis. He is then declared the loser.

The penalty must be decided before the game and could be anything from streaking in public to giving hand jobs to homeless people.

For the rules it is suggested that pube shots are not allowed.
K, guy, lets play Slap Dick, no pube shots!

Someone who is equal parts dunce and douche-bag.

Someone who has nothing to offer.
I can't believe that slapdick George Bush was a two-term president.

Unless they thought I was a total slapdick, I should get the job.

A "slapdick" is simply that guy or that girl, who thinks he/she is all that. Some dude walks in a party with a fake tan, popped collar and acts like they know everything about everything, yet not one person there cares what they have to say, gives them attention or wants them there.
"Yo who brought that slapdick to the party?"
"What a slapdick"
