A particularly rough form of coitus in which the female partner is caused back pain, possibly even sustaining injury.

Used in the mid-1990's hip-hop scene. Common use did not catch on, possibly because of the derogatory connotation of referring to women as objects of abuse and disposal.
From Notorious B.I.G., "I Love the Dough":

Make the best CD's and the best tapes
Don't forget the vinyl, take girls break spinals
Biggie be Richie like Lionel...
