"so legit" song

Song "so legit" with subtitulos in English so to be able to appreciate a little better the lyrics of this song and thus to be able to understand why it is believed that Lana wanted to offend gaga.

Although my opinion is that simply Lana could be at a bad time or whatever and as we know she had a little problem with alcohol, but that does not matter and tell me what is your opinion about this song?
