A hybrid of "gargantuan", "humongous" and "fabulous", to create a term implying a size greater than all three.
Original usage is credited to author Alan Peterson in "Radio World" newspaper in the early 1990s, describing hand tools used to repair and maintain a century-old carousel in Holyoke, Mass. (see example of usage below)
(excerpt from article) "...trying to fix a telephone using a garmongulous screwdriver meant for the carousel upstairs..."
(other use) "He wasn't just fat... he wasn't just 'circus fat'... this guy was garmongulous!"
another term for a station wagon, mini-van, or any other kind of vehicle that is targeted at the "family" demographic(also M.A.V.)
"Tactical advantages aside, the M.A.V. is top of the line for the holy warrior troop transport manufactured by the Church of Latter Day Saints Military Industrial Complex. Also great for family trips...to heathen lands."
12 step recovery jargon referring to someone new who talks about how great life is, now that they'resober. Usually meaning that the person is out of touch with reality.
The new guy seems pretty happy for a dude who has no job, no money and no family. He must be on a pink cloud.
