Man of course I’m a one trick pony
Cause I’ll be screaming on these whores 'til I’m hoarse!
A one trick pony is someone that only has one real talent.
Taken literally, Eminem’s one trick as a pony is to turn into a horse — which is relatively clever considering that ponies are relatively timid, so the moment you think that Eminem has gone soft he’s gonna turn into a horse and beat your ass to that finish line
Taken figuratively, Eminem’s one (indisputable) talent is his ability to rap, and therefore you’ll be hearing him through your speakers until he’s hoarse (has lost his voice)
This is also direct acknowledgment of the excessive hate he’s received amongst his fan base because of his ‘yelling’ delivery he has had on post-Recovery songs (especially).
It’s a way of telling his own fans to shut up: Eminem is gonna do what the fuck he wants to do til HE decides he has had enough.
