Cepsi

When you get a cumshot to the mouth and wash it down with pepsi due to the lack of mouthwash.

Destiny's thirsty, maybe I should give her some cepsi.

Cepsi

The mixture of coca-cola and pepsi. Except there is slightly more Coke than Pepsi. Sometimes done for a unique flavor.

Person 1: Why are you mixing that Coke with that Pepsi?

Person 2: I'm Making Cepsi... duh

Person 1: Oh right, I knew that. People have said this before, Iv'e heard this. Yea I do it all the time, yea.
