pitstop

— When a driver is told to 'box, box', they're being instructed to make a pitstop. This is because 'box' sounds more distinct than 'pit' over the team radio, so there's less chance of confusion leading to an error. The word itself refers to the painted box outside a team's garage where pit stops take place, although some argue that it hails from 'boxenstopp', which is German for 'pit stop'.
