I'm a French exchange student in Brazil, the struggle is real

Yes, but that's how I learnt english, also from movies, series, games (mostly) and other sites like funsubstance

Was it a challenge to filter out internetish?

Yes, also learning the meaning of acronyms like lol and wtf took a while XD, in the end you have to read a lot and try to figure out words by context and if you can't, ask someone or in the most extreme cases... google translate the word and try to use it on context :)

That was me, forgot to sign in.
