When you accidentally touch someone else's body in an inappropriate way, such as if your hand touches someone else's butt while walking. Often leads to embarrassment and awkwardness for both people.
*Naomi and Nicky walking along, Nicky's arm swings too far and hits Naomi's butt*
Nicky: Oh god, I'm sorry!
Naomi: Freudian Slap!
If it were to occur repeatedly:
"Stop Freudian Slapping me!"
Nicky: Oh god, I'm sorry!
Naomi: Freudian Slap!

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.

When you masturbate with cash and shoot your load into it then slap it onto a female's face so that it sticks. Generally, more attractive females get larger denominations of money slapped on.

A 6+ person slap, where 1 person holds the slap-ee and 5+ others run at full speed behind each other, slapping the slap-ee one after another, acting like train carriages behind the first person. This is done most effectively when the slap-ee's head is held firm so they cannot shy away from the on-coming hands. A Train Slap is usually called upon when somebody has done something wrong and deserves severe punishment.
Guy 1: Dude?! Did you hear that Matt got an 8 person Train Slap for hitting on Marc's girlfriend?
Guy 2: Awwwww dude! That woulda' hurt like sheeeeeeet.
Guy 2: Awwwww dude! That woulda' hurt like sheeeeeeet.

Rhythmic, wet clapping noise made by repeated pounding of the loins against the naked buttocks of another while in the shower.
I walked by the locker room and heard the distinct sound of a Sandusky Slap coming from the shower stalls.
