reply-all horror
/rɪˈplaɪ ɔːl ˈhɒrər/
CommonThe collective dread when someone hits Reply All on a large email thread and the inbox flood begins.
Usually describes the chain reaction, not just the first mistake. The second-order horror (everyone replying all to say 'stop replying all') is the real joke.
