when you are making a chocalate shake for your friends; you add milk, chocolate ice cream and then you add a nice footlong turd. And to top it all off you put some whip cream and a nice little cum shot on top.
bryan: Kelsey im makin you a shitshake!
kelsey: cool i'll give it to Amber!
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.
