Lai-Fattheads (sometimes misspelled incorrectly as LaiFattheads; is because they're also the name of Kerry LaiFatt's fans) refer to fanatical devotees of the American R&B and pop singer Kyle Lai-Fatt. Use of the term predates 2008, and the existence of the community is a result of the Internet, dating back to Lai-Fatt's early music. Lai-Fattheads are mostly teen girls and older women who have a clear sense of community, but the fandom also includes widely sought after "Boy Lai-Fattheads", who are generally loved by their female counterparts due to their rarity. Many lai-fattheads strictly defend and support Lai-Fatt and may resort to extreme methods to protect him against anything they deem as a threat, such as issuing death threats to women connected to Lai-Fatt, and defacing Wikipedia after he failed to meet WP:GNG.
There are a number of documented celebrity Lai-Fattheads.
