The Nickmeister is the name used by a male love-meet.net user in Grand Theft Auto IV. No matter how many times Niko Bellic contacts him, he will never date him. He is a stereotype of a male in the southern US and/or college with excessive machismo. He is implied to be the brother of Matte Black (he describes an annoying, effeminate "art freak" brother like him), although they're both 21.
- His online name may refer to The Stifmeister, a character in the movie American Pie.
