A Transtesticle is a woman who has had a sex change and now has a thong dong. Transtesticles can usually be found trying to slam beers with the guys at a local bar, arm wrestling, and like flannel shirts.
Transtesticles are also known as: manginas, thong-dongs, switch hitters, and have many other names
A affair in which one or both people have recently come out of a painful divorce/long-term relationship; somewhat of a "practice run" for the next serious relationship. More meaningful than a fuck buddy or friend privilege, a T/R is monogamous, and involves close friendship, sexual relations, and often genuine love, but no potential for permanence. Frequently arises between people who were already acquaintances, and is the relationship-equivalent to a halfway house for broken hearts on the mend.
"I think Jeff is absolutely amazing and I would love to go out with him in the future, but I'm still healing from my divorce and this transitionalrelationship with Dillon is all I can handle right now".
A transition person is the first persion you date during and/or after the ugly ending of a long term serious relationship, or possibly a drawn out death of your partner. They comfort you through the pain, self doubt, insecurity and other difficulties. Then, as you heal, they are a reminder of that terrible time and pain, so you gently ease them out of your life.
