It's a few, but some of the ones I feel are undeniable:
"I ain't a killa but don't push me, revenge is like the sweetest joy next to gettin' p*ssy"<---this would be my vote.
"You a fan, a fake, a phony, a p*ssy, a stan, you 36 in a karate class?"
"Whips on my fists, houses on my wrists, your budget on my neck, your spouse on my dikk"
"my nikkas listen cause hell have no fury like a woman scorn
A cemetary full of mothafukkers got not knowin'"

-matter of fact that whole song is powerful as f*ck
"I finally figured it out, Magic mouth is used for suckin'
Roxanne Shante is only good for steady fukkin'
MC Shan and Marley Marl is really only bluffin'
Like Doug E. Fresh said, "I tell you now, you ain't nuthin'"
