A strong slap given out of annoyance or meanness which leaves the recipient slightly dazed and confused.

From the Malay phrase "penampar Jepun" to describe harsh treatment by Japanese soldiers during the Malaysian occupation of WWII.

In WWII the japenese use to slap P.O.W's execively as a means of interagateing their suspects. So, the term Jap Slap became popular in that era just as a reference to slapping someone.
HAHA you got Jap Slaped by the cops.

A traditional Jap Slap from the 1980s is a special move where you perform a crouch (preferably with a knee slide beforehand) and release a powerful judo chop directly at the end of the victims penis (from the Greek 'πέος') ergo the name of the maneuver which refers to the racist slang 'Japs Eye', referring to the urethral meatus. If delivered with enough force it will also hit the testicles (otherwise known as the goblins purse) with sufficient force as to make the victim kneel over and cry for a bit. If successful the victor can walk off with his arms raised high and shout 'Jap Slap'. However, this variation of the Jap Slap may be limited to the region of Essex in the UK.

Flipflops. Nicknamed JapSlaps because Jewish-American-Princess's wear them and they slap their feet.

The action taken to punish a person for a silly or stupid mistake, often in a playful manner. The name derives from asking the unaware victim to place his or her thumbs on the outer corners of the eyes and stretching the eyes to simulate an Asian appearance. Then the slap can be adminstered without a flinch diverting the blow.
I Jap-slapped my brother when he admitted to my new wife that we had a stripper at my bachelor's party.

To strike someone -- who *really* has it coming -- in the face with the back of the hand. JAP = Jewish-American-Princess.
