To strike a person, usually on the head, with both hands on either side of the head

Oriental fighting based on martial arts either in movies or in real life where someone gets right proper slapped.

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..

When backhand some bitch for pissing you off and the knuckle marks and laugh at them when they are on the ground crying like a little child
