Dave Bonta's "Limp" is a tiny picture of a flag hanging dead still, with no wind to lift it. The first line says it is "too great to stir," which could mean the flag is simply too large for a faint breeze, or that its size and importance make it weighed down, unable to move. The poem doesn't say which, and that ambiguity is part of its pull.
The comparison that follows is the striking part. The flag is like "a new carcass / not used to any airs / foul or sweet." A fresh corpse doesn't react to smells or breezes, and the word "airs" plays on both meanings: actual air and the pretensions or attitudes people put on. The speaker seems detached, even a little dark-humored, treating a symbol that usually stands for pride as something lifeless.
The mood is quiet, stagnant and slightly grim. The poem suggests a deflated, indifferent view of the flag, though it never states an opinion outright.
