Top Definition
An alleged female on the internet who intentionally posts pictures of her scantily clad self, types sexual innuendo on message boards, and otherwise openly flaunts the fact that yes, she is a female, on the internet. All this is done to gain popularity on forums and to attract attention.

The nerd hag often uses more than her fair share of smiley faces.
