This is when one who may be diagnosed with autisim takes a plastic alchohol bottle (karkov) and bends the plastic top at a 90 degree angle. Then next step is to have a friend or oneself flip the 1.75 of vodka upside down into his or hers mouth with the one who is recieveing the gerbil shot puts ones hands up with the flick of a wrist and keep the wrist bent as if they are a gerbil. The point is to guzzle as many gerbil shots as possible out of the bottle. It is also optional for the one recieving the shot to act as if they are running on their gerbil wheel before recieving.
Oh my gosh I could totally go for a gerbil shot. I heard a rumor that Gerbil shots can cure AIDS. Lets take em!
