Shitscrolling 

Scrolling through content on social media while pooping with the intent of making it easier to poop because you envision yourself pooping on the faces that appear in the cheerful selfies and/or art, etc.

A: Jessica's instagram is so pathetic I can go shitscrolling thru her selfies every time i take a crap.

B: meh, Jessica isn't all that special in being pathetic. I shitscroll through everybody's photos.

Carla took her Rat Terrier Clyde for a walk and came across a newly fertilized lawn; Clyde promptly started shitrolling to get the scent all over him

Shit Scrolling 

Scrolling through social media during a bowel movement.

My legs fell asleep while shit scrolling too long.
