The gap between the price you expected and the price you got
A market order takes a moment to fill, and if the price moves in that moment you pay something different. Thin order books and fast markets widen the gap. A limit order removes it, at the cost of possibly not filling at all.
Expecting $1,000 and filling at $1,005 costs $500 on 100 shares.
