On Twitch, as a streamer ends their own stream, they can send their viewers to another streamer's channel. This practice is known as a raid.
To begin a raid, a streamer types /raid in Twitch chat, along with the name of the channel they want to raid. Viewers then see a message that says "StreamerName is raiding OtherChannel with ### raiders." At that point, viewers can choose to leave the raid if they so desire; those who remain will automatically be sent to watch the about-to-be-raided channel.
Typically, streamers use raids in a positive manner, to promote other streamers' content and attempt to grow each other's audiences. However, some raids can be trolling and toxic, in which case they're often labelled brigades.
