2. (Physiology) - An inverted orgasm, where the penis backfires, blasting fizzing molten semen right back up the semeniferous tubules, through the Tubular Bells into the Shatner's Bassoon. Ignorance of anticlimax in Victorian times meant that male pregnancy was poorly understood, with auto-bonked self-pregnant males often suffering scepticism and discrimination.
