In order to butterfinger, one must first excrete loose, watery bowl movements (diarrhea) through their anal canal. As this process is taking place, a second party (preferably a lover) inserts their philanges into said anal canal thus acquiring their lovely brown butter. The second party may then do what they please with their sweet juice.
Bartholomew: yo, bruh, I don’t feel so good. I think I have diarrhea.
