Not quite. It started with a meeting invite that was accidentally sent to everyone. The meeting was for the Amazon Wallet team (I think they did something with payments, etc.) for whatever work they were doing at the time.
Most people ignored the meeting invite and just deleted it, but someone hit "Reply All" and said something to the effect of "I know this meeting invite was not for me, but I wanted to make sure that whoever was supposed to get it did not miss the meeting."
From there, it turned into a "Reply All" storm with lots of people replying all with "Please do not reply all".
Others thought it was funny and sent memes. One guy was so bold to promote his indie rock band that was taking off.
The incident is famous and became known as "Wallet", but the name comes from the Amazon Wallet team.
