If its a woman you are trying to impress, just tell here you make a lot of money, I doubt she cares what you really do.
If you don't want to say you're a trader, say something like "investment manager". If you want to be really obscure you can just say you are a "liquidity provider".
I always enjoy a good horror story, so whenever someone asks how I make a living I tell them I'm a day trader and not only does everyone kind of know that that is, they all have a great horror story about their friend/spouse/uncle/cousin, etc. was day trader and lost everything. Somehow these stories always involve leverage to the hilt...
A money man. A man who knows what money is and is not. A man who is specialized in extracting money from other people. Who exploits the inefficiencies that others create. There is no morality in my profession. I use every legal means possible.
