꼬

Southeastern 'what is it?' — and shouted 'Go!'

Two different things are spelled this way here. In southeastern (Gyeongsang) speech, -꼬 ends a question, above all in 뭐꼬 / 머꼬 'what is this?' — 진짜~ 뭐꼬! 'seriously, what is going on?' Separately, four lines are simply the English word 'Go!' written in Korean letters and shouted as encouragement: 꼬! 꼬! 꼬! The two have nothing to do with each other; tone and context separate them.

Register: Gyeongsang dialect; or shouted English
