That's valid reasoning, if you ask me.
Black Korina is attractive, but it's not unobtanium. You're looking for a behavior rather than an appearance, so you're using it properly. Call it a "sleeper" <grin>
From the Merriam-Webster...
4: someone or something unpromising or unnoticed that suddenly attains prominence or value <the low-budget film became the summer's sleeper>
What a random comment haha. That put a smile on my face
. But do you agree Korina is a little bit superior?
We used to call certain cars "sleepers" when we were kids because they had monster engines in them but were otherwise unremarkable. You could surprise somebody on Telegraph Road by pulling up next to some dingbat's tricked out rag-ride and blowing them away at the light because they didn't think you had what it took to take them on. These days, it happens to ricers all the time.
