For the pain and it poured every time when it rained
A play on the term ‘when it rains, it pours,’ meaning that bad things don’t just happen; they happen in full force. Every time something went wrong in their relationship or if Kanye and Amber fought, it would always be a big blowup and the emotional trauma was just as bad.
It could also be a hint as to how Kanye liked to deal with such incidents — by drinking alcohol in large quantities (pouring liquor for each emotional rainfall).
