EVIL pro tip: invite your friends to a sleepover and specify that you have enough sleeping accommodations for everyone then when they arrive be like "yeah all the other beds disappeared like ghosts" so everyone has to sleep in this one massive bed but it's really more like 3 california king beds attached at the sides and all your friends reluctantly accept and spread a rumor to different random people that you and x friend slept together (technically true) to cause chaos. once the rumor has reached a sufficient number of people such that your other friends are discussing the rumors like the climax of an episode of a mediocre sitcom, propose to all of your friends at once then immediately say lol get fucked and ride away on your motorbike, never to be seen again
