On this day, Nov. 12, in hip-hop history...

1991: Bronx-bred rapper Tim Dog made his debut with his 1991 album Pencillin on Wax, a project that arguably lit the match to the infamous East Coast vs. West Coast hip-hop beef of the '90s.

During a time when group's like Compton's N.W.A. were reigning the hip-hop charts, East Coast acts were growing frustrated with the neglect. IN March 1991, Bronx's Tim Dog dropped the track "Fuck Compton," one of the most blatant and scathing diss tracks ever directed towards West Coast. "Fuck Compton" made fun of West Coast fashion and took direct shots at rappers like Eazy-E, MC Ren, Ice Cube and Dr. Dre.

"Why you dissing Eazy?/Cause the boy ain't shit/Chew him with tobacco, and spit him in shit/I'll crush Ice Cube, I'm cool wit Ice T/But NWA ain't shit to me/Dre beating on Dee from Pump it Up/Step to the Dog and get fucked up/I'm simplistic, imperialistic, idealistic/And I'm kicking the ballistics," spit Tim in the second verse of the song.

The song was produced by Ced Gee of Ultramagnetic MCs and although it didn't gain much radio play due to it's explicit nature, "Fuck Compton" became a rally cry for the East Coast and a hit in the clubs. Dr. Dre would later respond to Tim Dog on the song's "Fuck Wit Dre Day" and "The $20 Sack Pyramid" off his own debut album The Chronic in 1992.

Pencillin on Wax as a whole was released by Ruffhouse Records and is filled with plenty of shots at California MCs besides the main single. The intro to the album samples N.W.A.'s Niggaz4Life intro and there were skits in which Tim beat up DJ Quik and bagged up Death Row singer Michel'le. To date, "Fuck Compton" still goes down as one of the craziest diss tracks of all time, which solidifies the album Pencillin on Wax as a moment in hip-hop history.
