What i analyze about the song is that in the beginning of the song the girl came in and saw that her boyfrnd and his homeboy always come into his/her house to play games. she told him and his hb to the out and that she dont want him anymore. so he and his hb and other frnd went out to find another gf or to just live without the girl. i guess the girl got tired of hime being lazy around the house. the boy said he was flxing and stunting on his ex which was his gf to make her jealous about the way she treated him b4. and then in the end it seem like she came crawling back to him and apologized and all that other stuff and drove off in a car. The End
I guess formal and informal refer to two types of essay - you can write a formal essay where you avoid conversational language and such and where you need to be very professional, or you can write informally where you don't have to think about such things, it is very casual.
