geek can refer to anyone excelling in knowlege or skill of a certain activity or subject.

In Israel it's one who was dunked head in the toilet and flushed on by the basketball heroes of the school and who set dates with girls that didn't show up in highschool. He joined the army glad 2 not see those jerks. in bootcamp the other soldiers held him down on the ground to fart on his face. After bootcamp the computer geek served a shit job at tel hashomer or lotem base cleaning the personal toilet of the disciplinary officer who spent 20-30 yrs eating only burgers. Once the israeli computer geek is out of the army he goes to university, does well and goes on to a msc and phd in computer science. On the way the computer geek makes himself excuses like "no time" for having had no dates in his life nor going to the gym or excersizing since bootcamp. Once the israeli computer geek is a lecturer it's a bit different. He can be an asshole in his own way giving bsc students weekly tasks where only the geeks like him who suffered in highschool and bootcamp don't lose part of the grade before the exam. When the Israeli computer geek is an educat the divorced 33-46 yr old women consider the man they meet at the pub since he isn't as dumb, drunk or broke as their electrician or nut salesman ex husband and an asshole to young bsc students counts as an asshole. Finally when the Israeli computer geek is in his way on top he also gets a good fuck when it no longer matters. A computer geek lecturer is the lecturer for any computer course you take in university who gives you shit.

I am geek so i know how do desribe them , geek tend enjoy thing that are consider unpopular (for me its Star Wars , World of warcraft etc.) Geeks do not have to be smart , that would be a nerd, both nerds and geeks have friends but a geeks friends would probably say "Hey Albert i just got PvP Epic Armor on my Gnome warrior!" while a nerds friend would say "Hey Albert i just Got a A+ on my math exam.

An attempt by an individual to defend overt jumps in logic made by film-makers and authors in science fiction and fantasy movies or books. To go beyond what is obvious (or semi-obvious) to the average move-goer or book-reader to defend what was poor planning on the part of the creator. Be it anachronisms, poor research or cheap shortcuts to move a plot along. Geeks are FAMOUS for coming up with excuses as to why something in a favored movie was not self-evident to one of its critics. Some twisty "clever" explanation outside of what is available in the actual film is the geeks explanation. Usually some thought that a character was having about the situation, or some magical math that's only available in the sci-fi world in which the genre occurs.

seemingly lame and pathetic balding teachers who probably use that disguise to hide their real identity as a paeodphile and sex predator. they should be avoided at all times. especially when they grin

A person who loves math, and enjoys doing hard math problems for fun or for challenging him or herself. Sometimes if a person in Math Class in school that is a math nerd, may say for a assignment, "Math Rocks!" and the other people say "shut up nerd!", "Math sucks bum!", "Nerd!"
