Eli vs. Envy

Freestyle Eli
I'm retarded mayne, I can't deed it
so scared that even a "scaredy" cat frightened him
Eli is saying he is not surprised Envy came out to participate in their rap battle, because he has already supposedly announced he is homosexual - that he previously came out (what gay people call it when they reveal they are homosexual) for a gay parade
dental is used to generally refer to the dentist, since a dentist does dental work. in this freestyle rap battle, Eli is suggesting Envy's teeth are crooked or otherwise in need of dental work, which is an insult to his appearance
this may mean Eli is descibing himself as being paid to entertain women like lesbian television personality Rosie O'Donnell might be at a pre-wedding celebration (he may mean bachelorette party)
