Crotch. I do so like the word. (And you thought I would be commenting on the afterlife. Foolish you.)

Crotch also refers to a place where something forks, so just be glad the classic poem doesn't go, "Two roads crotched in a wood, and I - - I took the one less traveled by." And you just know I'm going to be referring to them as a crotch in the road from now on.
