A Two Mooser: is when a man and women man and a man or woman and a woman take both of their thumbs in a 69 position and put them in the others asshole and pull it open and then insert their tongue into the ass

The thumbs in this sense become the antlers and the tongue is now considered the moose thus giving you the Two Mooser as it involves two people doing it simultaneously in the 69 position
Tom and sally did a two mooser last night he said it was the best thing in the world!
