I should make a thread sometime of my favorite secondary characters from slasher movies.

I'm going to start this thread with Barb from Black Christmas (1974)! Margot Kidder is perfect as this perpetually drunken dirtbag who steadily gets consumed with guilt over her possible role in her friend's disappearance.

Going to update this thread approximately "whenever I feel like it." Secondary characters really determine whether a slasher movie works for me and there are a lot that I like.
