Human butterfly

When you press your anus against a willing participant’s anus and shit with such force that the excrement goes inside of the second party. The two stand in a way so that the group’s shadow looks like a butterfly.

My partner and I wanted to try the human butterfly, but my balance is horrible.

Human Butterflying

An instance in which two or more people (human or otherwise) touch their individual butt-holes to that of another person.

During the covid-19 quarantine Pom Pom Purin and Macaroon passed the time by Human Butterflying.
