A catfisher is the name coined to a bottom dwelling human, who spends a great deal of time on the net in various locations, luring people into a falsely based romance. A catfisher uses fake pictures and bogus information. Often has low self esteem and simply is not happy enough with their image to present it to people that they deem out of their league, and turns to faking other people instead. Other reasons for fraudulently representing people include doing it to boosting one's self esteem and playing people they would otherwise not even get to speak to. In short a catfisher is someone who performs the act of catfishing.
