Bantifreeze
1) When someone tries to get some bantics going by doing the first act (acting like antifreeze on a so-far boring night out)

2) Term for alcohol consumed before the bantics begin (or so that bantics seem like less of a challenge).
1) 'I had to do some bantifreeze at that moment or the night would have sucked'

2) 'Pass me some of that bantifreeze'
