Flabbercrombie 

An excessively overweight male sporting a tigh-fitting abercrombie and fitch t-shirt. Key signs denoting a Flabbercrombie are belly portruding from the underside resembling a sweaty muffin, and fat, flabby arms poking from the short sleeves which could be mistaken from overwhelmingly large frankfurters.

Steve: After gaining approximately 40 pounds, I decided to cheer myself with a shoppin trip to Abercrombie and Fitch to purchase a t-shirt.
John: Your t-shirt can barely grip onto your fat, sweaty body, I could even go so far as to say you are an absolute Flabbercrombie.

Flabbergooning 

Gooning while in a state of shock or surprise. Could also refer to having the urge to goon when shocked.

The police tased him during his goon session therefore he started flabbergooning.
