this word has its roots in Satanism. It is said that in the 16th century, red headed Satanists (gingers) would use the name to help identify others who worshipped Satan. Today, the word is still used to help Satanists communicate with each other. For example, one might put 'crewfan' in his Xbox Live gamertag, or in his Twitter name.
Chris: Hey whats your Xbox gamertag? I want to play you in FIFA.

Chris: Mine is Crewfan11
Johnny: You fucking devil worshiping crewfan piece of shit! I should have known you were in league with Satan when I saw your fucking bonfire ginger hair!
