look up any word, like bae:

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.
Dude, I heard Kyle was so drunk last night that he let Steve and Al give him a stinky Twix!
