The act of holding a woman's boobs by the nipples, pulling them together and inserting a dick or some other phallic object between the resulting cavern. If desired the dick can then be inserted in her mouth as well. *Note: this can only be done with big titties. Small titties result in lots of pain for the girl.
Dude! I totally got some rocket sex from that slutlast night. She had some of the biggest tits i've ever seen... next to ur mom that is.
To solve a dispute (usually when two chicks want the one dude), rockem sockem sports sex is initiated. Generally, the dude will instigate the rockem sockem sports sex, in which the two girls will sit upon the dude (one on the dick and one on the face) and box until there is one left standing who is crowned the winner.
However, after all is said and done, the dude is the real winner and the chicks lose. Suckers.
Girl 1 - "Yo, he's mine!"
Girl 2 - "uh uhhh, back off bitch, he's my man!"
Dude - "Girls, please, there's only one way to resolve this... Rockem sockem sports sex."
