wearing a flat brimmed hat, trying to make a fashion statement but actually looking like a total wanker.

Sports stars have flat brims only because its a brand new hat whacked on their head by a sponsor,

and leaving the sticker on your hat when its no longer brand new just adds to wanker level.
check out that tosser with the old dirty flat brimed hat, he's put a new starter sticker on the brim thinkin its cool, what a brimmer!!!
