I adore weird words. In my previous job I used to regularly get told off by my boss for using words like 'extant' (which isn't that weird, unless you're in construction apparently and then no-one knows what the hell you're on about). And I once suggested to a particularly obnoxious colleague he might want to make use of an open window and defenestrate himself (I was young, angry and somewhat stupid).

But, all that aside, there are some wonderful words out there that I think need more time in the literary sun, so here are a few oddities that I've pulled from the OED. 

abomasum - the fourth stomach of a ruminant, such as a cow or sheep

absquatulate - to leave somewhere abruptly (sounds more like something's leaving abruptly after a bad meal, see also badmash)

badmash - Indian a hooligan (but could also be served with bad sausages and gravy in a bad pub)

Barmecide - illusory or imaginary and therefore disappointing (not comitting suicide in a bar)

bilboes - an iron bar with sliding shackles, used to fasten prisoners' ankles (nothing to do with plurality of Hobbits)

callipygian - having shapely buttocks (no-one's ever described mine like that to my knowledge)

chiliad - a thousand things or a thousand years (this question came up in trivial pursuit the other day, and one of my kids knew it. I didn't. And people say schools are failing. Pah!)

colporteur - a person who peddles books, newspapers, or other writings, especially bibles and religious tracts (not the singer)

deglutition - the action of process of swallowing (sometimes synonyms are kinda bleaurgh)

doryphore - a pedantic and annoyingly persistent critic of others (who should usually be defenestrated)
