painting your toenails
A sneaky way to tell someone you're about to give them the worst facial of their life.
My cousin said she was painting her toenails, and I knew she was coming for me.
He told his mom he was doing his nails, but I saw him eating a sandwich in the bathroom.
She said she had a headache, but I know she was just pretending to paint her toes so she could make me suffer.
