Stephen Colbert's Vasca line of pharmaceuticals, from Prescott Pharmaceuticals, is proud to introduce the Vasca Band. A belt that you place around your neck that constricts your esophagus to prevent finishing your entree and crushes your trachea so you can't order dessert.
Side effects of Vasca Band include: stoppedness of breath, facial bluing and auto-not-at-all-erotic asphyxiation.
"Officer, this man was found next to his spilled sweet tea. He has a stain on his pants and appears to have suffocated naturally. Looks like another case of auto-erotic asphyxiation."
"Thanks, Doctor. That jacked up Ford F-350 with the truck nutz must have driven through the neighborhood again."
Lan and Vianca performed dual-erotic asphyxiationto the point that they both almost passed out from both the lack of oxygen and pleasure they were giving each other.
