I am many decades out of dating, and didn't even date that much, so I didn't really experience this though I did have one date with this guy who was all 'I think you're a really cynical person' in a way that implied he thought I'd be flattered he thought I was 'smart', when I'm not cynical at x all and I find cynicism often something people affect to try to look clever.
Have you ever caught out a bloke, IRL or online, being melodramatic, 'negging' or some other dumb move to try to make himself look intriguing but failing totally?
