A Goose Douche is an individual that orders Grey Goose Vodka bottle service at club due to the perception that the spirit imparts a certain level of status.
That Jersey guido thinks he's cool because he's paying $400 for a bottle of Grey Goose but most the girls in here realize that he's a Goose Douche.
Goober Douche: Someone highly annoying and/or stupid who is also a complete retard and doesn't know anything about what they're talking about who also wears white sunglasses!
