NOUN: The penis itself, as described in the above series of actions which together comprise the "Stinky Twinkie" maneuver. It is indeed stinky, as it has been in a woman's anus, and possibly as far as the descending colon. The reference to the Twinkie, a cream-filled tubular sponge cake manufactured by the Hostess Company, is pretty much self-explanatory; Since the withdrawal takes place prior to ejaculation, the "Twinkie" (penis) is still metaphorically full of "cream" (semen). Technically, the semen actually resides in the testicles.
Thus, as a NOUN, one can both HAVE a Stinky Twinkie and EAT it as well; and as a VERB, the act described above IS known as giving someone "The Stinky Twinkie"
USAGE AS VERB: "After a long while ass-fucking my woman, and realizing that I wasn't able to come, I yanked it out and gave her the old STINKY TWINKIE."
