I was given B by kakiphony.
1) Bellydancing - something I love to do and to watch. I first started over 10 years ago, but until a few weeks ago had gone 7 or 8 years without. Lately it's become all the rage to call it Middle Eastern dance instead, which I think is utterly silly given that it comes from a wide range of sources, not just the middle east.
2) Bones - the undercarriage of the human body. Also, a decent tv show.
3) Bauxite - a pretty rock that is fun to say. Go ahead, say it!
4) BoingBoing - one of my favorite websites. I've been reading it since sometime in 2000.
5) Bucket - a handy container to have. We have a bunch of them, in different colors and sizes. All plastic though, no metal ones at the moment.
6) Bailywick - I always envision this word as a kind of territorial flame.
7) Braille - a language of texture. I had an older sister once, who was blind (she has since perished). She started teaching me Braille, and I learned more of it when I worked at the Tucson Association for the Blind and Visually Impaired. Neat stuff.
8) Bees - I feel an affinity with bees. In one of the places I lived in Tucson, bees used to find their way in, and get stuck in the carpet. I'd get them out & toss them back outside to fly.
9) Baklava - a delicate and delicious dessert, that I can no longer eat because of the celiac.
10) Beluga - white whales. A great word used in a great vignette by The Vestibules. You can hear it (and see a fun animation) here.
