Slightly slang term used by many (not all) transmen, or female to male transexuals to describe their phallus. The female clitoris grows into a small penis as a result of testosterone therapy. FYI, we all start out in the womb as female, and in the beginning, we all have a clitoris. It is the introduction of hormones in the womb, determined by our chromosomes, that determine our sex.
He had never been with a transguy before, but the idea of this guys hard, wet tranny cock throbbing in those tight, faded Levis was driving him wild.
Trannycore is the moeshit anime that transexuals typically like. It consists of a mixture of bland, cute flavor of the month anime (example: Miss Kobayashi's Dragon Maid) and anime containing trap characters that they identify as (example: Fate/Apocrypha). Usually they're very popular series and are no more than 4 or 5 years old. For this reason, something like Lucky Star or Yuru Yuri can hardly be said to be trannycore.
If you see someone using a character from these shows as an avatar, or otherwise identifying excessively with the show, chances are they're a transexual.
TrannyFucker is the name given to the soldier in a an infantry section who is presumed to be the most endowed or have the biggest dick . In order to combat the presence of such a male the other members of the section must convince this person to fuck trannies or at least try his best. For this to be effective a genuine effort has to be made by the lesser endowed section to get their more generously endowed section member or common nemesis to do this act ( of fucking a tranny ).
