The heir to the Samsung throne has widely been known to throw the craziest sex parties this side of Pyongyang. Thought to have been raised and educated in Boston, MA, the mysterious heir to the Samsung Electronics Empire has become infamous for his rockstar-eque exploits of females. He has been known to jump from city to city in his private jet sleeping with multiple women in between decadent meals. He has allegedly taken hundreds of thousands of women out to seafood dinners and has not once called them back. In sum, he makes the Dos Equis man look like Tim Tebow.
Jon got drunk last night and ended up in a hotel room with 3 Vegas strippers and a midget. Needless to say it was a Samsung Sex Party

A Mandatory Sex Party is a party where once you walk in the door, you are obligated to have sex. These parties often disguise themselves as costume parties, birthday parties, or baby showers. But THEN as soon as they entice people in the door, they are all "guess what this actually is? It's a mandatory sex party, bitch!"

Then the raping would commence.

this is a simple phenomenon, basically just what the words say: it is a party where it is mandatory to have sex -- with allie brosh.

variations have arisen whereby whatever girl or guy that is named becomes (he or she) with whom sex must be had if you want the free drinks and food etc
dave: did you go to the party last night?

dale: i went to the house, but i got there and turns out it was a mandatory sex party and i didn't have any viagara and, you know, i can't naturally get it done with non-asians. allie said just an hour or so of oral would be ok but i was looking around at all the guys who'd already been there a while and had their turn and i kind of thought i'd be better off just going to a movie.
