My bumper they're scratching at the back of my trailer
Like I'm itching to get hitched
There are three wordplays on this line:
1.The first one is the association of attached (line above), latch, and hitched.
2.Then he makes a relation between scratching and itching.
…they’re scratching at the back of my trail-uh…
3.And finally hitched (common slang for getting married) is also used as wordplay to say all these women are after him like he’s trying to get married now.
If we look at the song as a criticism of the rap game (the bitch Em is talking about being rap) it could mean that all/ the majority of the other rappers are trying to catch up on him, to follow his trail, but they won’t because they aren’t at the same level.
