i recently read this book about medival times and ever since , whenever I get mad , I say Corpus Bones ? I’m not even sure what it means , but it seems to fit my vocabulary. not to mention the fact that in fifth grade , we played a game of making up different words and using them alot , now those words have been stuck with me for about 10 years. The only words that come to mind now , are " prettyful and Fucksocks ( dont ask), not to mention adding “osity” to any word that wasnt an adjective
Along that line, I sometimes refer to “penguin logic.” This is from a cartoon in which a penguin is depicted thinking: “Penguins are black and white. Some old TV shows are black and white. Therefore, some penguins are old TV shows.” It sort of fell out of use since the people I’m trying to communicate with have no idea what I’m talking about.
Recently, I’ve been using jackass as a verb, as in, “It’s shaping up to be another jackass day, I can feel it.”
Another is scrommy. This is short for scromulous, which my mom picked up off a 19th century tonic ad that was purported to cure “warts, boils and other scromulous cruptions.” We used it a lot when we were turning over nasty rental properties: “Oh man, that place is really scromulous. What I need you to do is scrub down that scrommy kitchen so I can paint.”
I threaten to “thwap” my students–which is good because is sounds vaguely menancing without them having any idea what it actually means (I always picture an open slap to the back of the head).
It is also possible to feel schlubby–i.e. sloppy and generally un-spiffy. I often go to the grocery store in schlubby clothes and hope to hell that no one I know sees me.

You’re actually using it as an adjective, here. A verb would be “I was jackassing last Tuesday and I fell out of my chair,” or “Hey, Phil, care to jackass?”

Obscure words that I overuse:
Eschew (sounds like a sneeze :))
Sesquipedalian
Defenestration
Callipygian
Quotidian
Weltschmerz
Niminy-piminy
Vituperation
In addition, I always find myself attaching “uber” to the front of adjectives. For example:
“Your scarf is ubercool.”
“That song was uberlame.”
Does anyone else do this?
When I was a kid there was a ad on TV for an air fresher/cleaning product. It was an Australian ad (and I’m sorry but Aussies do tend to run-their-words-together) The woman declared “Something smells Julinka” …years later Iworked out it was “Some smells do linger”, but if you ever fart near me you have “made a julinka”.
I never ever ever gave up groovy. Groovy is a very groovy word…always will be.
If something is really really bad (it sucks) I may be heard to utter “Well that sucks farts out of dead monkeys bums”. I learnt that one off my very classy brother.
If you ever do anything to annoy me you may be given this little thought “May your ears turn into arseholes and shit on your shoulders”
Thanks to SDMB I am now awfully fond of asshat and meatpickle.
