terminal growth

(noun) - pertaining to the maximal length or growth of a man's facial hair. Word origin: Commonly mistaken with 'terminal value' from the financial vernacular but earliest use is believed to be from a Greek parable about a young man's journey into manhood. Nikolai, from the island of Garofali, was sent by the elders off the island for 'aner teleios' (grow into manhood). Those sent were not allowed to return until their beard had stopped growing, signaling the god's acceptance of the boy into manhood.

"No, my beard won't get any longer. It's at terminal growth."
