A computer whiz-kid who knows all the computer tricks and boasts their up to date softwear and programming knowledge.
Note: it does not mean they are smart!!!
Often a term used by those that are feeling lonley i.e have limited friends or those that wish to express Jealousy (especially if it is in a constant way) or those who want to detract from their geek like image.
The kid sitting alone only with a laptop for company mistakenly called the maths genius a geek.
