What is Fantabuloso?
1.
An adjective given to describe something that is both fantastic and fabulous, but with a Spanish twist to it so the speaker sounds smarter than he or she actually is. It is said with a rhythm to it i.e. fantabu-lo-so, or with a posh accent i.e. fantabuloso, dahling.
Alternatively, it can be used as a pun to describe the taste of a common fizzy drink.
"Scrubs was fantabuloso last night, did you see the bit when she slapped him?"
"Mm-mmm, those bubbles of carbon dioxide are just fantabuloso in my mouth!"
