From what I could hear, it's, "We ferocious" at second 12 and perhaps, "What - we ferocious" at second 22. The correct way to say it is, "We're ferocious" but it's a common theme in pop songs and youth slang to drop the 'to be' verb. It's fine in a song or talking to friends, but I don't recommend you use this grammar with anyone in a serious situation. In our house, if our teenage kids talk like this, my husband corrects them and tells them they sound like idiots!! Maybe we're just old...

Thank you soooo much, you helped me a lot!

I think I understand! She says, "I am a this-and-that kind of girl, a real mixed bag" (second 12 -16) which means she does a little bit of lots of different things. She doesn't focus on just one thing or person. So she likes and does 'a little bit of this' and 'a little bit of that'. A 'real mixed bag' means the same thing. Second 27 to end, it sounds like she makes a few non-word sounds and says, "Lots of nuts in that bar" which means lots of crazy people in that bar. It's probably a reference to the fact that some bars have bowls of nuts (the food) to eat, but she's making a play on the word because a 'nut' can also mean a crazy person.
