Published September 29, 2026

Spam is internet slang for unsolicited bulk messages, borrowed by early 1990s Usenet posters from a Monty Python sketch where a cafe menu is overrun with the canned meat3. The label stuck as junk email began flooding ARPANET inboxes, becoming one of the oldest pieces of online vocabulary still used daily.

Overview

The word doubles as a noun for unwanted mail and a verb for sending it in bulk. In the Python bit, a waitress reads off dish after dish containing spam while a chorus of Vikings shouts the word until real conversation is impossible. Netizens on early IRC channels and Usenet groups picked up that image to describe posts swamping threads with repeated garbage.

Over time the label widened to cover any high-volume digital nuisance, from bulk pitches promising to enlarge male anatomy to bot-driven forum floods4. Automated spambots do most of the sending today, which is why volume can spike overnight. On image boards, spam is used deliberately as a raid weapon, and 'sagebomb' floods bury target threads by keeping them from being bumped3.

Origin & Background

Platform
ARPANET (early bulk mail) / Usenet and IRC (term coinage)
Date
1993

The earliest documented bulk online message came from Gary Thuerk, a DEC marketing rep, who on May 3, 1978 tried to blast an ARPANET announcement about the new DEC-20 machine to every address on the West Coast1. Recipient Einar Stefferud later explained that the sender was untrained in SNDMSG, so addresses overflowed the To, CC and Subject fields into the body, and many intended recipients never even got the pitch1. Users still complained loudly, and DEC was formally reminded of ARPANET's appropriate use policy1.

The word 'spam' itself came later. Usenet and IRC users in the early 1990s started shouting 'spam spam spam' at unwelcome posters as a direct nod to the Python skit, and the label stuck to any bulk unsolicited posting3.

How It Spread

By the mid-1990s the word was doing legal work. It appeared in rulings such as CompuServe Inc. v. Cyber Promotions in 1997, one of the first US cases to treat bulk commercial email as trespass to chattels3. Brad Templeton's archive of angry replies to Thuerk's 1978 blast shows the same complaint pattern that has followed junk mail ever since, including a celebrity spam-defender jumping in on the thread1.

Spam is also used deliberately as a weapon on forums and image boards, with video coverage of the tactic showing how flooding a site can drown out conversation or bury threads entirely2. Whole outfits, from Spamhaus to volunteer filter maintainers, formed to fight it, and email providers built entire industries around detection. Urban lexicons still record the running joke about penis-enlargement pitches obfuscated with spellings like 'exp and y00r man-rod' to slip past filters4.

How to Use This Meme

Spam works as a noun ('my inbox is full of spam') and a verb ('stop spamming the channel'). Common conventions include tagging any repeated, off-topic, or bulk-commercial posting as spam, whether it comes from a bot or a human trying to drown out other voices. On forums and image boards, users often call for mods when a thread is being spammed with sage posts, promotional links, or copy-paste floods.
