A portmanteau describing a style of facial hair that is an amalgamation of a goatee and a mohawk. It should be relatively thin in width and (ideally) start below the lip, continue over the chin, and end just before the Adam's apple, although many variations are possible. Generally, the longer the hair gets, the greater the effect.

Persons that embody a lifestyle medley of Gothic and Hawaiian clothing and vibes. Typically someone headbanging to Misfits while in flipflops and a Tommy Bahama pineapple shirt.

Guy 1: That looks like the most depressed and suicidal person in a parrot shirt I have ever seen.
Guy 2: Nope, they are just Gothawaiian...pretty common actually.
