This is a sexual act involving three woman laying down in the shape of a triangle. The first woman menstrates into the second woman's mouth. The second woman then chokes up the menstration through her nose into the third woman's anus. The third woman then squirts the menstration from her anus back into the first woman's vagina.
"Instead of putting your finger down your throat to throw up, just grab a few chicks and tell 'em to try out the dirty dutchman trifecta. That should do the trick."
