This is a legendary passive-aggressive move right here.
A woman on Twitter named Angela Brisk posted her method for sticking it to any guests she has over to her house who she doesn't really like. It's not clear why she's having people over who she doesn't like, but that's not the point.
This woman 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. Now...I don't know about you...but that seems like a lot of work. Why not just not invite people you don't like over to your house?
