Thin edge of the wedge
A minor change that begins a major development, especially an undesirable one. For example, First they asked me to postpone my vacation for a week, and then for a month; it’s the thin edge of the wedge and pretty soon it’ll be a year. This term alludes to the narrow wedge inserted into a log for splitting wood. [ Mid-1800s ]
