1. The reason you don't eat chocolate ice cream.

2. The only thing in the world that will take away your desire to watch porn.

3. If you don't already know, you still don't want to.

4. A video that's starts out as a seemingly harmless lesbian porno and turns into a disgusting fuckfest when the two girls dump a massive load in a single cup and take turns licking it, drinking it and spreading it all over themselves. Then they continue their lesbo action, except covered in shit.

5. Another reason you don't want to live on this planet anymore.
The two girls and a cup video made me barf at first sight.

To prove my manliness, I ate chocolate ice cream after watching two girls and a cup.

Get the two girls and a cup mug.
A sexual act in which two girls mimic the time honored tradition of the wining hockey team drinking champagne out of the Stanley Cup, by inverting a male participant with his legs spread wide, thus creating a cup out of his anal orifice from which they will then urinate into and then drink out of, sometimes with a straw.

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!"
