Coming from old war movies wherein the American Soldier is being interrogated by the Chinks... basically as the American soldier starts to say something he is backhanded... This repeats until he emotionally breaks down...This word also comes to mind when i think about some of the stuff jessica simpson says... The other thing that comes to mind when i think about Jessica is hot steamy sex.

American Soldier : "Sho- *SLAP*"...

A quick, compact baseball swing popularized by Japanese big leaguers such as Ichiro Suzuki, So Taguchi, Akinori Iwamura, amongst others.

Most effective with a left handed batting style, the jap-slap has become popular with Hispanic and American Major Leaguers such as Juan Pierre and Brett Gardner.
Akinori just put the ball in play, jap-slap it if you have to.

to slap someone in the crotch wilst only hitting their japseye. Quite a skillfull feat and has to be done right otherwise it is just like getting hit in the balls. Performers of the move should be comended even by the victim.
"awwww did you see that jap slap mark got john with... it was sooo skilful musta hurt like a bitch."

its a very light backhand slap to the forehead..

this causes ones eyes to squint briefly --like a jap or chink.

its more to get their attention than to punish..
when the ole lady gets things backwards once again-

a quik jap slap sometimes gets her to focus on the issue..
