East coast slang for an annoying pest who no matter how much you try and get rid of, persists and continues to annoy. Usually every "clique" or friend group has one and although they put on an act while around the "gu"; they ignore him/her at all costs and joke about how much of a "gu" that person is. In addition to having no friends, the "gu" is the epitimy of grossness and therefore has zero game with the ladies.

Get the Gumug.

Get the gumug. One that bullies uncontrollably by choice and intends to scar for life. Tends to be a dick at social gatherings whilst drinking all the goods and eating everything in sight. Cares about his friends but will also threaten to destroy them at any given time. One might even say that a Gus won’t buckle his seatbelt no matter how many dings go off during a drive. A Gus may typically be someone who has anger issues that trigger an overload of drinking or vice-versa. A standard Gus trait involves road rage 100% of the time. Many fucks will be expressed and will often result in body slams and punches to the face. Under the surface, a Gus will have a soft heart and loving arms. A Gus has untapped potential when dealing with the opposite sex. Anything and everything can happen when a Gus is in sight.
