Short for right testicle.
My righticle hangs lower than my lefticle.
Righticle is a false term used in short for right testicle.
Although it is not an actual word as when the word "Lefticle" was established, it was determined that "Righticle" did not flow well enough off the tongue to be made a word.
"Lefticle is left testicle, so is righticle right testicle?"
"No, Right testicle, is right testicle."
