When I unexpectedly found myself single after a long-term relationship imploded last year, I did the Tinder/OKCupid thing for a bit. One of the more amusing experiences was when I had planned a date with a girl and was telling a friend about it. At one point after describing the girl's profile, my friend stopped me and asked about some detail before pausing and telling me "she's a smurf! I know her!"

(For those unfamiliar, Ingress players have tongue-in-cheek epithets for the opposing team. Green team are "frogs" and blue team are "smurfs".)

The date didn't lead to anything as I don't think she had any romantic interest in me, but it was definitely a funny point when during a lull in conversation I paused and gravely asked if it was OK for her to be on a date with a "filthy frog" and she busted out laughing.
