A foamer hat is any type of hat (typically a baseball cap) that is worn by a transit enthusiast. Transit enthusiasts, sometimes called foamers tend to wear hats while filming or riding trains. Foamer hats usually consist of a metro, or commuter rail line or branding, covered in enamel or metal pins of the transit kind.

Day where idiots foam over trains to the excitement of nobody. Nobody likes foamers yet they still exist and therefore like anything else, get a day because they are so well known and disliked.
