The act of shitting in a tinfoil pie container and then ejaculating on top of it, then you preferably get your mother, sister or cousin to share it.

When someone goes to the gym and spends 90% of the time on their phones scrolling through social media

Much like the Alaskan Pipeline, one must first shit into a confom or another type of pouch. Once you thoroughly mix it with lubrication (preferably flavored) you freeze it and wait. This is when the fun starts, as you grab a close relative (parent, sibling, cousin, grandma, etc.) and forcefully fill their orifice(s) with the aforementioned sack until one or both of you shits from excitement. Hence, the Alabama Mudpie.
