Extremely hot and sloppy oral (or non oral) sex. Like the Gawk Gawk/Gwawk Gwawk, but more wet and steamy.
Person 1: Person 2’s mom gave me the slavvy tavvy and a couple STDs.

Person 2: Just don’t fuck my mom 😀✋

The Slavvy Tavvy is an extremely wet and sloppy way of performing oral sex.
Person 1: Bro that bitch's mom just gave me the Slavvy Tavvy! That shit was fire!
Person 2: My man! Let me hit her up next time.
