Pizza Cum 

The flavour of one's cum after over-consumption of pizza. Comes with variety of flavours depending on the toppings on said pizza.

James eats so much pizza, when he gets a blowjob, the giver always tastes the flavour of "pizza cum" when he blows his load in them making them swallow because it was that delicious.

cum-on-a-pizza 

cum-on-a-pizza is a masturbation game that guys play, similar to cum-on-a cookie, except all the guys jack off on a large pepperoni pizza and the last dude to have a cumgasm, has to eat the cummiest piece of pizza -- and the guys keep doing that until the pizza is gone.

We played cum-on-a-pizza and I kept losing, so I had to eat a lot of cummy pizza -- yum!
