Beaver do him
A beaver is a pussy, remember?
“Cleaver” and “damn” are simple word plays to go hand-in-hand with “beaver”. “Cleaver” is the last name of the boy in “Leave it to Beaver”. As well, Beavers build dams — hence the “don’t give a ‘damn’”
If you purchased the album the lyrics are inside and you know the word is “beaver”.
In an interview with Eminem and Royce, right after the albums release, that specifically state the word is indeed “beaver” and there was no intention of dissing Justin Bieber. As stated here at 4:30.
It does not say “BIEBER do him”
(From the Hell: The Sequel Digital Booklet. You may need to zoom in. It clearly says “beaver do him”)
