Stellacious is a mix between stellar and bodacious. Normally in reference to pastel colored things, but not exclusively. Can also reference a beach lifestyle, or radical things (sights, events, etc...)
Those pastel orange shorts are stellacious bra!!! But that sentence would be said, "Those shorts are stellacious bra!!" Or if the surf is epic, you could say, "the surf is stellacious bra!!"
