Dau ddiffiniad o 'geek' o'r We:
 
"a person who may be very smart yet lacks the social graces of those who are considered cool , a "computer geek" is someone who spends too much time on the computer and has no social life"
"Derogatory term for a person with limited social skills, and usually strong technical skills. While anybody can become a nerd, geeks are born, not made. The difference between a geek and a dweeb is that dweeb has no redeeming qualities."
 
Mae i'r gair "smart" yn y diffiniad cyntaf ei ystyr Americanaidd, sef "galluog", nid yr ystyron Saesneg/Cymraeg "trwsiadus" neu "golygus".
