I have read the text of this song. What the piece of shit it is! I suggest you to try to find another lyrics to learn Russian. I am a native Russian speaker and i don't know what the phrase you asked about means.

Hey! the word "угореть" is mainly used in Russian slang. It has two meanings: 1) to make fun of someone by ridiculing that person. Usually, the ridiculing is thinly disguised. Я просто угораю над Максимом и его глупыми идеями. Ты думаешь это правда? Я просто угораю над тобой! 2) to go bonkers for - Let's imagine you like a rap band and you can't live without listening to Its music. In the given context, the verb "угорать" indicates the high level of your devotion to the band. Я угораю по музыке Снуп Дога. Я знаю ты угораешь по Ювентусу и его капитану Буффону.

Most common use - to laugh about smth really loudly, to be happy about smth , to lake smth to craziness. Originally comes from "угар" - to be in state of intoxication initially from smoke, later from drugs. It has a hue of adoring and being under the impression of smth in a way as from drugs. This sentence can be translated as "I'm good, but I wanted to know how the evil is "

скорее всего тут имеется ввиду, что парень хотел напиться до крайней степени, хотя он хороший и правильный. Скорее всего такой оборот для рифмы.

Так и не =never update----> sorry, it was meant for another question!
