In the Computer Dictionary , a bigot is a person who is religiously attached to a particular computer, language, operating system, editor, or other tool. Usually found with a specifier; thus, "Cray bigot", "ITS bigot", "APL bigot", "VMS bigot", "Berkeley bigot".

Real bigots can be distinguished from mere partisans or zealots by the fact that they refuse to learn alternatives even when the march of time and/or technology is threatening to obsolete the favoured tool. 

It is truly said: "You can tell a bigot, but you can't tell him much."

Bigot  1590s, from Fr. bigot (12c.), in O.Fr. "sanctimonious;" supposedly a derogatory name for Normans, the old theory (not universally accepted) that it springs from frequent use of O.E. oath bi God. Plausible, since the Eng. were known as goddamns in Joan of Arc's France, and during World War I, Americans serving in France were said to be known as les sommobiches...

But the earliest French use of the word (12c.) is as the name of a people apparently in southern Gaul (on the now-doubtful, on phonetic grounds, theory that the word comes from Visigoth).

Sp. bigote "mustache" also proposed as a source, though the sense is not adequately explained. Earliest English sense is of "religious hypocrite," especially a female one, and may have been influenced by beguine (a member of a lay sisterhood, or the modern social dance). The sense extended 1680s to other than religious opinions.

However, the crowning misdefinition has emerged. It's probably the approaching weekend, maypoles and a general air of spring, but Gaberlunzie was finally offered an aisles-rolling comment from a friend.

"Quite simple." said the friend. "Someone told me that it was all over the internet - Gordon Brown was overheard calling an old age pensioner a 'big titted woman.' "

Could the field day have got any bigger?
