The sex position in which the girl is laying flat (emphasis on laying completely flat) on her belly with penis entry from behind. This position often enables the female to work the muscles in the region resulting most likely in an overpleasurable time for the man involved, thus causing premature ejaculation.

To have sexual intercourse with a person who's lying on her (or his) belly. More precisely, to "bone" a "prone" person.
Then she turned round on the bed and spread her buttcheeks, so I started to pronebone her like a madman!
