I overheard a conversation the other day. Lady's divorced, got the house here and was asking this good old boy who is a Appalachian transplant who is a shade tree mechanic (only kind we have here) about the power steering belt squealing when she turns. Good old boy said it might be as simple as belt dressing.
Few days later she's in church and tells him "I put BLT dressing on it like you said, and its making noise even worse now."
Good old boy says "BLT dressing? What's that"
She says "What you told me. BLT dressing, so I put some mayonnaise on there."
Good old boy slapped his knee, "BLT dressing. I tol' you belt dressing." Belt comes out BLT in his Appalachian dialect. "Blt dressin'"
