Get the reverse sided double peanut buttermug. When you attempt to let out a large toot, but instead are left running to the bathroom with a little more down there than you wished for. Can damage underwear beyond normal repair.
Aitanna just let out a tooter butter! Oh goodness she's going to need to shop for new underwear soon, she's running out!

Get the Tooter Buttermug. The sweat right between a mans testicle sac and leg that has condensed and gathered lint, hair, dirt etc... Usually the stinkiest/manliest part of the mans body. Although it is gross, women will always be attracted to it.

Get the Duck Buttermug. An attractive, young, and voluptuous (usually plus-sized) woman with a sizable and smooth chest and/or backside that looks enough to pet and squeeze like a pet bunny. Somewhat similar to BBW.
