The process by which a person (male or female) is approaching the climax of an orgasm and begins to get very excited. At the actual climax they start to laugh hysterically to the point where they vomit all over themselves and then immediately follow it up by sobbing uncontrollably.
John: I had a fantabulous roller coaster last night with lindsay.
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!"
When your expectations of greatness are so far exceeded, there seems to be no adequate word
There are no words stupendous enough to describe how great that night was. When we fucked for an hour and then she blew me, it was fucking fantabulosome.
