Sunday Ass 

Irritated sphincter caused by over-active bowels due to consuming large amounts of draft beer Friday and Saturday. Usually stems from not abusing alcohol during the week, then compensating for the hiatus by binging through the weekend. Sometimes involves a hemorrhoid or two.

#1. My friend could not go mountain biking with us last week because of his Sunday Ass.

#2. Why does that bar have to have Miller Lite specials over the weekend? I end up with Sunday Ass every time I try to save a little coin.

Fingers in his ass Sunday 

Basically, a joke that originates from a shitty video in which sans and nagito komaeda dance with the hallway that has sans in it in the background, with the song "fingers in his ass" playing in the background, which was discovered on a Sunday, afterwards creating Fingers in his ass Sunday.

"damn, it's fingers in his ass Sunday! Time to watch that video again!"

Sunday church asshole. 

Those who only go to church on Sundays with fancy clothes to see who they can meet there and look like good people. Not really interested in religion or being good guys.

-"Where's John? He never comes to play Tennis with us on Sundays."
-"He's a Sunday church asshole."
-"Bah, what an asshole."

Sunday Morning Asshole 

A swollen, chaffed or sore asshole that can only be achieved after a solid ass-pounding friday and saturday night. Most common in insecure drunk women, dope fiends, inmates and Justin Beiber fans.

Austin awoke that morning to find his asshole swollen and practically rubbed raw from all his guido buddies after a spectacular weekend of fist pumping and partying on the Shore, a textbook case of the sunday morning asshole.
