Descend the stairs beneath Central Square’s beloved dive into a low-ceilinged room thick with applause, snapping fingers, and the smell of cheap beer, where Boston’s longest-running slam has crowned poets every Wednesday since 1992. The night opens with a poetry-only open mic at 8, builds to a fiercely contested slam, and closes with a featured reader. Arrive before 8 if you want a seat; the cover is a few cash dollars and the energy is electric. 21+.
