Noun; An anal orgasm occurs when you hold in a monster shit for too long and finally let loose. After enough time passes, the levvy will break on brown river, and the feces flood will pour out. The quality of an anal orgasm (or simply "AO!") is dependent upon the girth of the ass tremors which create this unnatural disaster. When the eruption occurs, it will feel plain magical, but be forewarned; it is best to be in the vacinity of a T-bowl or else you're going to have a grizzly poo-lava mess on your hands.
"Holy Cow, Brandis just had an anal orgasm in the bathroom that registered a fuckin' 12 on the Richter Scale! Not only am I still shaking from her not-so-humble rumble, but the smell is just plain fuckin' killing me."

The achievment of sexual climax through recieving anal sex alone, without simultaneous stimulation of the vagina or penis.
Bret stroked his lubed cock into his pre-op shemale friends ass deep and hard. "She" (Sarah) cluched the bed sheets and began to moan louder and louder until "her" thighs began to quiver, toes curled, and eyes opened wide at which point "she" screamed out "OH GOOOD!!" and without either Sarah herself nor Bret having stroked her cock exploded in orgasm and squirted cum several inches onto her big fake breasts. Sarah then came again without any touching of "her" cock and this time Sarahs eyes rolled back into her head and she lay on the bed shivering in a semi daze. Sarah knew then what it was to have a purely anal orgasm.
