The party guy. The dance floor king. The snob. The totally shy intellectual. The bike fanatic. The Vegan activist. The music producer. The wannabe actor.
The German IT guy. The foreigner IT guy who speaks Ruby and C++ but not a word in German. The cool entrepreneur. The tattooed bartender. And so on...
Questions about your very specific traits of personality and your not so common activities etc. (for example, in my case: my tattoo project, Veganism, my goal to become trainer, wearing only in Purple and Black, the colour of my hair).
Questions that one can use to approach you and ask you out, like your best holiday. The next movie you want to see. What do you usually drink. Where do you like to eat out. What do you think about being friends with the opposite sex. Your phone number. Bingo.
