adult handshake 

Any sexual act involving one's hand and a man's genitalia. First heard (possibly) on the American translation of the Japanese children's show "Shin Chan," where two detectives need to feign homosexuality in order to keep their cover.

Hey, at least I wasn't the one giving an adult handshake to a male gigolo!
