From the German "weltschmertz", meaning "world pain." Purposeful mispronunciation has altered it to its current form, possibly due to its hollow feeling, not unlike hearing your own echoes in a well. A fairly popular word for a deep, lonely, though passing depression, used among college students in the Asheville-Black Mountain-Montreat area of Western North Carolina (though most of the users are not originally from that area).
Man, the last couple days I've been drinking, and I can feel something coming, like wellsounds.
