The proper term to use for the penis of a gay man when his penis is of smaller than usual proportion. Its originated because the size of a twix candy bar is smaller than the average size of a human's penis and it is also brown in color, similar to feces, which gay men have on their penises because they engage in copulation up the rectums of other men, and animals.
I thought I was gonna get some good dick in my snatch, but then I found out that guy has a twix dick.
