A popular beverage of whorish-sluts looking to mingle. Generally they will prepare their own "tinis" by tugging of a nice shaft for a few minutes until the cumtini mixer shoots into their cumtini glass. Served on the rocks with a green olive. Yum.
Paul: "You ready for my cumtini?"
Heather: "Am I ever! Shoot me a nice one right into my cumtini mouth!!!"
