A shartsum or having a shartsum is when you and any amount of people gang-bang with eachother but instead of cumming inside of each other, you shart! You can shartsum with any amount of people you want. You can even shartsum with yourself if you wanted to! (Not sure how that’s supposed to work) but yeah you can also invite people to your shartsum and grow it💞 the bigger the shartsum, the better!
