An Oral Don is the action in which a man, while having intercourse with a woman, reveals an Oral B toothbrush and begins slowly penetrating his own anal cavity with it. The term is a combination of the words Oral B and Big Don; Oral B of course meaning the toothbrush, and Big Don, which is a man whom enjoys leisurely playtime within the confines of his own anus.
