ㅂ쇼

Clipped 십시오 — gruff but friendly

-십쇼 is -십시오 worn down in speech: still a polite command in shape, but blunt and matey in delivery. 자주 불러 주십쇼 형님 'have me on again, hyung', 주무십쇼 형님 'get some sleep, hyung.' Four of these six lines end in 형님, which tells you where it lives — a younger man talking up to an older one he is comfortable with.

Register: blunt-friendly, man-to-man
