rectumspect 

The thought of regret one has during the first bowel movement after eating an extremely spicy meal.

My asshole burned so much today when I took a shit, in rectumspect it probably wasn't the best idea to eat those spicy chicken wings last night

rectumectomy 

rectum removal either by actual surgery or in a comical sense - by removing an "asshole" from a room, group or other situation.

When Kenny kept making off-color comments and acting the part of a complete asshole, Jimmy Ray decided to remove him from the room and performed a rectumectomy for the good of the group.

rectospect

One's feelings about the previous day's food, after it has come out the other end.

That jalapeno burger I had last night tasted really good, but in rectospect, maybe wasn't such a great idea...

Rectospective 

The view of life perceived by someone with their head firmly planted up their ass

John had his head so far up his ass that it gave him a unique rectospective
