Pfizer snowball

Like a regular snowball, but when your homie has copped the Covid 19 vaccine so you are sharing the heard immunity.

Person 1: Man I can't go outside yet, I haven't copped the Covid Jab
Person 2: I got you man, I'm already immune. Lemme give you a Pfizer snowball

Person 1: How were you eligible for a vaccine so early?
Person 2: What vaccine?
