When a person is slapped twice across the face, and the repercussions are equivalent to that of two atomic bombs- Hiroshima and Nagasaki style!

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.

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..
