Fhqwhgads
From Homestar Runner Wiki
The legend of fhqwhgads (pronounced fah-HOO-guh-gads) began with the Strong Bad Email "i love you". The email appeared (to Strong Bad) to be signed "fhqwhgadshgnsdhjsdbkhsdabkfabkveybvf". This was probably just random typing: Many letters in this name are next to each other on a typical English-language QWERTY keyboard. In attempting to reply, Strong Bad shortened the unwieldy name to "fhqwhgads".
Later, he wrote a song and The Cheat created a music video about fhqwhgads, "Everybody to the Limit".
Strong Bad gives Homestar Runner, Coach Z and Strong Mad a lesson in pronouncing "fhqwhgads" in an easter egg at the end of the Strong Bad Email "sibbie". The correct pronunciation is fuh-HOO-gwah-gahds.
In Main Page 22, the Biscuit Dough Hands Man pop-ups say "fhqwhgads", using the robot voice from the song.
