"Boof it like Kavanagh" sounds like a parody version of "Bend it Like Beckham" where a young white guy starts partying and taking bribes after being inspired by his favorite Supreme Court Justice in spite of his parents actually giving great advice on how to be a decent person
You let it melt, go to the drive-thru liquor and get a half pint of Jim beam, and mix em while getting on the freeway in your dually F-250 which you’re using to haul 3 cases of bottle water back to the subdivision from Sam’s Club.
I think you're supposed to squint with one eye, scream "ACK ACK ACK" as you crush the cup from all sides with your hand, and then catch the plug of shake-goo in your mouth.
Maybe with a spoon? I could imagine drinking it like a fully liquid drink, but that sounds like it would get pretty messy pretty quickly, like when a cup of ice spills onto your face.
