“Bust” has few different meanings. In this situation, Brotha probably means three of them:
Bust as in to rap ie “bust a rhyme”
Bust as in to shoot a gun ie “bust a cap in his ass”
Bust as in to orgasm ie “I busted a nut in her face”
He is dissing other rappers by saying that they rap like homosexuals. I have never heard a homosexual rap, so I personally would not know.
Considering this song is about killing people and what not, Brotha also disses other rappers by saying that they shoot their guns like a homosexual would. I also do not believe I have seen a homosexual shoot a gun, so I am not sure how poorly they would handle a weapon.
And finally, Hung puts out a diss to rappers by saying that they are actually homosexuals because they orgasm with other homosexuals.
“Adam and Ed” ties the line all together. Any Christian should know that Adam and Eve were the first two people on earth. Christians who think they are funny often say something along the lines of “Adam and Eve, not Adam and Steve” to preach about how homosexuality is wrong and yadda yadda. Hung uses “Adam and Ed” simply because the rhyme was more convenient for him.
By the way, with this photo evidence, we can see that Adam was in fact black.
