Although it originally appeared on Tear Da Club Up Thugs' 1999 album CrazyNDaLazDayz, “Slob On My Knob” is essentially a Juicy J solo song as he raps both verses and produced the song as well. In the song, Juicy raps about having sex with two different women and having both encounters go awry. Juicy told VIBE he wrote the song when he was in 11th grade.

Despite being released in the ‘90s, the song has had some staying power and has inspired a number of Vines and memes.

Juicy J made a sequel to this song (which has similar lyrics and follows a similar format) which appeared on Three 6 Mafia’s Underground Vol. 2: Club Memphis.

In an interview with Complex, Juicy talked about making the original and the sequel saying:

That was a song I wrote when I was in 11th grade. And the song was—it had two different kind of beats. The first beat I had with it was just, whatever. People was fucking with it, but they wasn’t on-it-on-it. So I changed the beat up.

I played it in the club one night, the next Sunday, as I was setting my equipment up, people were coming up like, ‘Yo, Juicy, you gonna play that song you played last weekend?’

I was like, ‘What?’ They was like, ‘Slob on my knob or something like that.’ I was like, shocked, ‘You really liked that shit?!’ They’re like ‘Man, hell yeah. Play that song!’ So the second time I played the song? Whole club went crazy!
