Regardless of what any of the Klingons in this thread claim, I suggest following S.P.O.C.K.'s advice - never trust a Klingon.
Goth Klingons would dress in ballerina tutus, dye their hair blonde and wear pink jackets. Teenage Klingons would do their utmost to upset their parents like human teenagers do when they rebel against the older generation.
Surely that's punk Klingons. Or would punk Klingons go "Excuse me, what kind of IPA do you have on tap?"
Interesting. I'm a lifelong goth and have just started learning tlhingan Hol, I think there might be something to this.
