Get the Nassmug. The act of performing cunnilingus on a girl by pulling the female's vaginal lips apart, then shaking your head violently and fully relaxing your cheeks and lips. Also, a sound effect like you are really going to town and getting dirty with this girl's vagina is welcome, and is almost 100% necessary for the woman's full satisfaction. Any saliva that falls out of your mouth while doing so is just added lubrication. Based from the character Boss Nass in Star Wars.
