tenesmus 

An overpowering, incredibly painful sensation of your “backdoor” demanding to defecate (aka drop a deuce, colon cannonballs, butt driblets, digested Crayola box), with the inability to produce any colon candy (aka stool, feces, fecal matter, waste) despite a valiant, laborious effort.

Butthole Spasms, period cramps in your asshole

“A lady and a man got into an argument, the woman started screaming about a pain in her butt and the man renounced her claims and stormed off…. The woman tried to yell, “ It’s not you, it is my tenesmus acting up.”
