When someone mixes 3 or more sodas together to make the cup look like it's filled with shit water, and having a semi good taste, and none of your friends enjoying what you just did.
Guy1: Go fill up the soda Guy2.

Guy2: *mixes Mtn Dew, Pepsi, and Dr. Pepper together*

Guy1: C'mon not Shit Soda again!
