After a big meal & great night of hot sex. When your girlfriend, whore, or whomever falls alseep, gently pull yourself from underneath your blankets & squat over her chest but don't be loud as she might wake up. Gently ease out your poop onto her chest & there you have it. A nice dump on her chest. Aka...Boston Heater
Last night when your mom fell asleep I gave her a boston heater.
