A Common term use to describe a sex act, preferablly done by an asian woman.
Towards the end of sex, normally before you blow your load, you pull out. The Asian then proceeds to make small karate-like jabs at your penis until, hopefully, you bust a nut.
Note: Can be done by any woman, but Asians are much more experienced in the art of dick dabbling.
Don: You lucky son of a bitch!
Phil: Thats the 4th Asian this week Mikey, and its only Tuesday.
Don: Jesus Christ Mikey, how DO you do it.
