In the OP's case, it was an honest mistake and a mutual misunderstanding, albeit with a lot of rudeness involved. First off, the word "turtles" in the girl's profile wasn't capitalized, so it most likely referred to reptiles in a shell, rather than fictional crime fighters named after Renaissance artists. Also, TMNT are more popular among guys than among girls.
However, the OP's example isn't entirely benign. I've seen instances where women feign ignorance about a topic as a "socially-acceptable" way of messing with unattractive men. Because it gives them plausible deniability, that they actually didn't know something, as well as a cheap thrill of making someone jump through hoops. Consider my own example, when I was chatting with a girl from a dating site, who lived in my town and said she liked hiking.
Aspie1: what's your favorite place to go hiking?
Woman: anywhere
Aspie1: mine's around the big pond at [Park Name], the one with the lion sculptures at the entrance.
Woman: wheres that lol
Aspie1: it's at [Side Street] and [Side Street], 2 blocks east of [Well-known Major Street].
Woman: lol lol i dont know where that is lol
Aspie1: k
That's when I stopped talking to her. I wanted to try explaining again, but quickly realized she was just messing with me, when she claimed not to know [Well-known Major Street] or the lion sculptures. So I decided to beat her at her own game the best I could, by simply saying "k".
Oh, and the proper spelling is "Michelangelo". You're welcome!

She might not have legitimate knew, she may be new to area or like me and not get out much, I’ve lived in my area my whole life’s but I hardly ever got to downtown so if someone started giving me directions based off downtown I’d be clueless
