bdelliumsex (-0.858)
An aromatic gum, like myrrh, that is exuded from a tree. The spelling above is not a typo, it is like one of the only words that sounds like it starts with a "D" but actually starts with a "B".
Kindergarten teacher: Billy, can you give me a word that starts with the letter "B"?

Billy: Bdellium.

Teacher: No Billy that starts with a "D"

Billy: No, dumb-ass the "B" is silent.
