The masturbatory act of propping oneself against a bedpost, couch, or bedside and rubbing the clothed penis against it repeatedly, in order to illicit an initial pleasure and an eventual intense, (or otherwise) ejaculation into the seams of the underpants. This, being usually an early form of conventional masturbation, does not at first neccesarily illicit ejeculation. Rather intense feelings of pleasure. Once sexual maturity is reached, and in the rare case the masturbator has not moved on to conventional masturbation, the ejaculation becomes a natural part of the bed-posting process. Most bed-posters move on to conventional masturbation before age 13, but in rare cases, continue well into their teens.

My best friend kevin, R.I.P. Coined this phrase in regard to his very good looking older sister, who he loved very much but as younger brothers do, insulted her as much if not more than his friends drooled over her sexy blond ass.
Me:Hey K, what's your sister doing this weekend?
Kevin: pfft, I don't fuckin know, probaby banging herself with her bed posts while listening to Bonjovie, she is such a bed post bitch!
Me: Bwahhhahhhahh da bed-potebit, da bed-potebit!
