A completely forgettable message board user. Somewhere there is most likely a factory churning them out by the thousands. You'll know you're in the presence of a forum rat when you read a post and get the sudden strong feeling that you've read the exact same post before. Main characteristics of a forum rat:
-Infrequent or nonexistent use of capital letters and/or punctuation.
-Bizarre behavior and use of the English language, which is often described as either ghetto, otaku, forum female, fanboy, or even l33t d00d, or a combination of the above.
-Avatar consisting of an anime or video game character, animated sprites from Metal Slug or Final Fantasy, or the forum default Homer Simpson picture.
-Username consisting of at least five numbers or underscores.
-Huge, ugly Photoshop abortion of a signature which may stretch the page frames.
-Terrible or nonexistent lack of personality
-Completely worthless, typical, or irrelevant opinion on anything.
Most forum rats are preteen kids, and often either a fanboy, wigger, jock. Though they come and go, no board is safe from them unless the admin only lets his/her friends register.

Get the Forum Ratmug. 
An individual (usually a guy) who is cheating and bounces back and forth between partners.
I came up with this in a dream!! I was dreaming about my boyfriend cheating on me. In my dream I asked him if his mother knew he was cheating. He said "yes, and she called me a rubber rat".
