- Skellington: variant of "skeleton." Pete pointed out it's also in the Cream song about the baby going down the drain. That song is awesome!
- Trumps: farts.
- Tupping: frickin'
- Smalls: undergarments
I've also been reading this great book about word origins that has some really wonderful, oft forgotten American words.
- Hornswoggle: origin unknown. But it belongs to a group of "fancified" words invented in the American West to poke fun at the sophisticated. Why can't our anti-intellectuals invent words these days instead of "Blue Collar Comedy"? The next three are also examples of this.
- Absquatulate: "to depart in a hurry." Faux-Latin affixes: ab- "away from;" -ate "to act upon in a specified manner." All around the made-up root -squatul-. Literally meaning: to squat away from. Hilarious!
- Busticate: "to break into pieces."
- Argufy: "to argue."
- Buckaroo: from the Spanish "vaquero," or "cowboy." Interestingly, we got the word "cowboy" from translating "vaquero," and "buckaroo" from mispronouncing it!
- Hosey: dibs. (Bostonian) Maybe from "call holdsies," maybe from the French "choisir," "to choose." But "I hosey shotgun!" is pretty neato.
- Grampus: kind of big fish in cold water. Also, an orc.
