A hipster looks for his hipster in the Montreal metro

I think I wrote it 1000 times on the blog, I'm a big fan of the section Flirt Metro from the Metro newspaper. Here is the most recent post that circulates quite a bit on social networks. A man looks for his hipster whom he met at the Montmorency metro station. I'm warning you right away, there are mistakes in almost every word. The key phrase "You wore a hipster mantle from the 80s. He didn't netait bo". The last sentence should also be explained to me, I'm not sure I understand!
