Most Helpful Girl
By dirty humour I mean being cheeky, or being jokingly sexually. I don't mean going full weirdo like dark humour (making fun of deaths or something).
There are some jokes I wouldn't go near the topic on a first meet, even if meant as un-seriously as possible, purely because you don't know where people's boundaries are. So, something like "what is the main cause for the rise in paedophilia? Sexy children." probably isn't a great first start.
Something more innocent like "I love what you're wearing. It would look perfect on my bedroom floor" is more the angle I would go for *thumbs up* :)1
