There is 'fit' on one side of the pond and then there is 'fit' on the other.
In America, 'fit' is less about overall good looks and more about the state of one's physical fitness. If someone is 'fit', they are in good shape; they are not necessarily an Adonis. For example, Dennis Rodman is fit; he is not (in my estimation) a looker.
In the UK 'fit' describes the whole attractiveness package. The US equivalent would be 'hot'.
Understanding this distinction, you will appreciate my embarrassment in the lift at work.
The lift doors open to reveal a group of men who work in my building, but for a different company. The building is a small building so the faces are generally recognisable, but for all intents and purposes, these familiar faces are strangers -- strangers of whom you might know a thing or two because you have unconsciously observed them over the past 5 years. It is late afternoon, and the men have started to let loose some steam. They each carry a bottle of beer; they have been laughing deep, manly laughs, which dim when the doors open to let me in.
The man in the front is a slightly nerdy looking chap who rides his cycle into work most days. He comes in early, as do I, so I have often seen him dripping in sweat before he has had a chance to clean up after his work out. He is not unattractive; he actually looks quite sweet in a nerdy, thin, sweaty, bike-riding way.
I am slightly taken aback to see that the bike-riding nerd is holding a pack of cigarettes.
"You smoke?" I blurt out before I can restrain myself.
He smiles sheepishly and shrugs.
"It's just that ... I always thought you were the really fit one."
Big hooty, manly guffaws resulted from his comrades. I went red. I have long known the difference between 'fit' and 'fit' but sometimes your upbringing gets the better of you and you end up telling a virtual stranger that he is really hot.
I tell my colleagues this anecdote and conclude "I'm certain I made the guy's day."
My Finance Director disagrees. "I'm sure you made his month!"
