A cycloptic red eye of death is when you poke your partner in one of their eyes and immediatelyejaculate into the other. Odds are, one eye will go blind and the other will be bloodshot.
Cyclopsing is the act of placing ones forehead gently or not gently on ones perineum aka the gooch, rotating the head by 15° to align one eye parallel to the rectum. The tongue is then used to fondle the sphincter till desired effect is achieved.
