Gah.

Okay, help. I'm drawing a total blank here. Does someone know what you call a word that sounds nice, but represents something really not nice? (i.e. friendly fire -- when you kill your own men in combat, etc.)

It's just on the tip of my brain.

ETA: Thanks labyrinthan_elf!

Had a trippy assed dream last night. And it was good. Only I can't remember any of it. Just that it was good. And trippy.
