The act of passing a kidney stone wile banging a chick in the ass. Hence the term "dirty rock".
I gave your girl a dirty rock last night.

Get the Dirty Rock mug.
well just an old rocking horse that you sit on and just rock back and forth and by then by turning it on it side, now that the person is warmed up and streched, the horse handles are inserted any way you want it anal or vaginal, it is generally used as a fat girls or guys plaything or love friend, after wards you suck the handles to get all juices and fecal matter off, so the tail is to wipe your ass and the smell keeps your friends and family away so you can enjoy the investment you have earned horse, fat chick, boyfriend,girlfriend, lovehorse
Damn, my rocking horse with a straw tail was sold to a fat chick for a long lasting love relationship. I am going to miss the long 23 hour riding days.
