psychopath woman on Twitter named Angela just posted her method for sticking it to any guests she has over to her house who she doesn't really like (why would you even have guests at your house who you don't like?).
Angela boils some hot dogs . . . then pours the water into an ice cube tray and freezes it. So when she's making drinks for the people she doesn't like, she uses the hot dog-flavored ice.
I mean, in the time it takes her to conjure up this ridiculousness and actually execute it, she could just ask the people to leave. Or excuse herself. That's a LOT of energy to go into being so petty. But you do you, Angela!
