noun
last act of the day; finale comic dialogue
Historical vaudeville/music hall usage: the final performance or comic dialogue of a program. Now largely replaced by sense 1 in modern contexts.
寄席では、大喜利がその日の最後の演目だった。
At the vaudeville theater, the last act of the day was the finale comic dialogue.
Originally from 大切り (おおぎり), meaning 'big cut' or 'finale', referring to the last act in a traditional vaudeville program. The modern spelling 大喜利 is ateji, likely chosen for its auspicious kanji meaning 'great joy and profit'. The shift to the current 'improv comedy' sense came from TV variety shows.
