A stinky Twix is when two males simultaneously insert their penises, side by side, into the anus of a third party, much like how a Twix candy bar has two bars side by side in one serving. Ideally, the two penises will emerge covered in some fecal matter, simulating the brown appearance of a Twix bar.
