That means he ain't fierce as this
Sometimes one’s being fierce/anger is brought upon by the pain one has felt.
The ocean of his tears could mean the pain Lupe’s endured throughout his life, the things he’s seen/been around. Especially being from Chiraq. All the nonsense occurring right in front of Lu’s eyes makes him mad. Also knowing Lupe, this may string further from Chiraq and onto all the crazy things happening in the world we live in.
Other rapper’s aren’t as fierce/angry as Lupe because they don’t care about situation in their cities as much as he does, and they don’t pay too much attention to situation in other countries. Lupe often refers to situation in The Middle East, he is mad that his own country of United States is killing innocent kids in Iraq, Afghanistan or Palestine.
Rappers haven’t felt the pain lupe has, thus they have never reached a level of anger that Lupe has.
