Purge: verb (used with object) [purged, purg·ing.] to rid of whatever is impure or undesirable; cleanse; purify. This seems like a harmless term…to anyone who doesn't know what it means for 5 Seconds Of Summer and their girlfriends. 24 hours ago no one thought the purge would be real until it was announced an hour before it started. Through panic, horror and complete and utter chaos, 5sos try to keep themselves and their girlfriends unharmed and alive. It's harder than you would think it would be.
