Two Styrofoam cups stacked one inside another containing Codeine Cough Syrup and Sprite.
My "two cups stuffed" last night cause me to be really tried this morning.

The ability to fill up two 8 oz. cups of semen with a single ejaculate. Takes mad skillz.
All the prostitutes in town talk about how much Ben ejaculates at a time. They call him Two Cups; One Toyam Ben.

Disgusting movie on the web. Two girls start licking each others chests, followed by one of the girls filling a pint glass with her own feces. The movie goes on to show BOTH girls licking and sucking at the contents of the cup. Later, one girl has a fine specimen that she squirts out of her mouth a few times before swallowing. THEN the girls start pulling the trigger and puking in each others mouths! WORST MOVIE ON THE WEB! INCONCEIVABLE!!
"My ex-girlfriend invited me to a friends' house to watch what she called 'Two Girls One Cup'... After watching it I burned all of my things, had my name legally changed, and moved to a new state."

The world's first viral Sheisse video.

Often shown to an unsuspecting viewer(s) in order to gleefully observe his or her horrified reaction.

(Spoiler Alert! The following reveals elements of the video's "plot")

Sadistic Asshole: "Dude... check out this video of these two hot chicks 'making out'. He! He!".

Said Asshole's victim plays the video "Two Girls One Cup": Idyllic music plays.... Two attractive women ... Standard Lesbian foreplay ... then, at about 0:30 into the video....

Traumatized Victim (horrified and at the brink of nausea): "Are they ... Oh my God, No ... I can't believe ... Are they really, IS SHE EATING THE OTHER CHICK'S POO! AND, OH NO, SQUIRTING IT INTO THE OTHER CHICK'S MOUTH! PLEASE, I CAN'T WATCH ANYMORE!"

Sadistic Asshole: "Oh it gets better. So much better, so much tastier."

... the two women, apparently fed-up (hah! pun intended) with eating each other poop, wash their fecal-feast down with a generous helping of each other's vomit; could there by a more fitting denouement?...

Traumatized Victim (shaking): "Where am I? Its sooo cold in here... My life will never be the same... My whole worldview has been decimated ... Someone, please hold me. I am so scared ..."

Sadistic Asshole: "Ha Ha! Isn't technology wonderful!"
