Flood, or rarely flad (from English flood /flʌd/ – "flood") – idle talk, messages in internet forums and chats that take up (in many cases) large amounts of space, or, conversely, consist of one word or several characters and do not contain any new, useful, or meaningful information. Sometimes, any off-topic is called a flood. For a chat, "flood" is the repetition in the chat of one or more similar phrases, more often than one message every certain period of time set by the moderators (for many chats, it is equal to 3 minutes).
Flood spreads both as a result of an excess of free time and with the aim of trolling – for example, out of a desire to annoy someone. Netiquette condemns flood and flame, as they hinder communication, mutual assistance, and the exchange of information. On many internet forums, special separate sections and topics are created "for flood", so that flooders do not spread their activities to other sections and topics.
Bow down and hear our cry,
Our earthly rulers falter,
Our people drift and die,
The walls of gold entomb us,
The swords of scorn divide,
Take not thy thunder from us,
Take away our pride.
G.K. Chesterton: English Hymnal
