Foamer

Someone who loses their mind over any train, usually a rail fanner or train buff. Most of the time they show no regard for their surroundings or to anyone really.

OMG, that foamer is so annoying! He's always yelling at the train station when a train passes by and throwing garbage on the tracks! GO LOOSE YOUR DICK SOMEWHERE ELSE

foamer

Orignally used to describe railbuffs, it now describes anyone who gets excited about something so much that they start foaming at the mouth.

Those geeks that play magic the gathering are foamers. They get so excited over one card that they start foaming at the mouth.

Foamer

The type of n00b who would use derogatory rail slang like SCAXliner or Amtrash, complains about the tuning of train horns, tends to endanger his or other's lives for a good photo, and angers railroad crews through his actions.

Also tends to spam youtube haters' channels, and tend to harrangue people via internet, cell phone, etc.
