With a general pejorative meaning of :
"a peculiar or otherwise dislikable person,
especially one who is perceived to be overly intellectual".

This word comes from English dialect geek, geck: fool, freak; from Low German geck, from Middle Low German. The root geck still survives in Dutch and Afrikaans gek: crazy.....
