Trainspotter - Derogatory term to describe anyone with anorak-like tendencies. Also known as Spotters or Rivet Counters. Is that bloke in the MT compound with a clipboard filling in his work sheet, or his he spotting number plates on Four Tonners?
Spotters are usually pallid forty-something virgins who still live with their parents. Those who actually have girlfriends have ones that are invariably munters. 'Tis a rare thing indeed for a Spotter to be nailing a babe - who might well have a thing for greasy-haired, sweaty no-lifers - who can tell? Funny ol' world, eh?
