What is Mentos Mudslide?
1.
The act of inserting a full package of mentos to the inside of an asshole during anal sex and - subsequently - adding your jizz and a glass of diet coke to the mix.
Drinking the ensuing mudslide is optional.
Jerry gave Melanie the best mentos mudslide ever; she gaped like a pro and the ass-geyser was at least 7in high!
