An expression that means that everything is amazing or that someone is perfect and nice with unicorns and rainbows on top. Or it could refer to the intake of too much ice cream, and shitting it out the next day.
e.g. #1 joe-" YO MY LIFE IS AWESOME"
bob-" shutup.. no one wants to hear about you shitting ice cream"
e.g.#2 frank-" Dude, I ate so much icecream last night that I was shitting ice cream this morning."
