2. (figuratively, by extension) A chaotic, uproarious, noisy place.Examples: "This taut, soldierly, professional story is something of a stranger among American novels about war making. Angry civilians have writ ten most of the best fiction on the subject, from “Three Soldiers” through “Catch‐22,” to make the point (with a good deal of literary overkill) that wars are mass insanity and that armies are madhouses."broadlyfiguratively
