The sound at the start of foreign athletics races before the 'bang', as opposed to 'take your marks' (onomatopoeia). nb. Word probably does not actually exist even with a similar, different spelling, it's just the interpretation of the noise and it's spelling (if it was a word/phrase) by one individual.
