Suit Wanker
A suit wanker is a member of society who tries to warrant their self-importance by wearing a suit all-day, every day. If their occupation, current situation or event they are attending does not require the wearing a suit and they are wearing said apparel, they can then be classed as a suit wanker, no matter how bad ass they look.
Person 1: Oh, Johnny's slipped again, he's becoming a suit wanker.
Person 2: What a suit wanker.
Person 2: What a suit wanker.
Full suit wanker
A person who wears a full suit (shoes, trousers, shirt, tie and jacket) when the occasion doesn't call for it - usually when that person is sucking up or pretending to be above their station.
Person 1: Who is that person over there?
Person 2: The full suit wanker? That's Tom, he thinks he's the boss but he's really just another volunteer.
