Although no specific meaning is ever given, it and its derivatives are regularly used as a derogatory term. There has been some speculation that the name is related to the word smegma; however, this has been denied by the writers. However, one of Kryten's lines from Smeg-Ups ("get out the smeg hammer and loosen up Mr Lister's underwear") seems to imply otherwise.
The term "Smeghead" is used very commonly throughout as an insult towards characters in the show.
