"Shook Ones, Part II" is the lead single from Mobb Deep's 1995 album The Infamous. The song is a sequel to the group's 1994 promotional single "Shook Ones", with similar lyrics, but less profanity. The original song is featured on the B-side of some releases of "Shook Ones, Part II" and was also included on the international version of the group's album Hell on Earth.

The original "Shook Ones" was released as a promotional single in 1994 as the debut single on Mobb Deep's new label, Loud Records. Producer Havoc stated,

What made us do a remix or a part two to the first “Shook Ones” was just our nervousness about failing because we had come off of the Juvenile Hell album, which wasn’t too successful. So, we were kind of paranoid. So, we made the first “Shook Ones” and was like, “Okay, that’s all right. But, let’s try to fuck with this shit again” just to be sure, and we ended up making “Shook Ones Pt. II.”

Havoc produced the beat for "Shook Ones, Part II" in his bedroom in the Queensbridge Houses in Queens, New York. The drums were sequenced on an Akai MPC60 and the other samples were sequenced on an Ensoniq EPS-16 Plus. The song samples a piano melody from "Jessica" by Herbie Hancock, strings from "Kitty with the Bent Frame" by Quincy Jones, and drums from "Dirty Feet" by the Daly-Wilson Big Band. The Herbie Hancock sample was slowed down and the pitch was altered to create the beat in the song. Havoc recalled that the beat was about to be deleted until Prodigy walked in and convinced him to keep it.

The narrative is told from the perspective of inner-city youths engaged in territorial warfare and struggling for financial gains. The phrase "shook one" refers to someone who may portray themselves as tough, but loses their nerve when faced with conflict or intimidation.

The music video shows Prodigy and Havoc rapping in different parts of Queensbridge at different times of the day. It also shows Prodigy rapping while driving a car, and Havoc rapping in the backseat of a car.

Havoc recalled: "Everyone on set was hype because the record had gained so much traction. The label, the around the way crew, Prodigy and I - we were all excited to shoot a visual for the record." He also stated: "The whole video was shot in QueensBridge, which gave it a more grimey edge and authentic feel. My favorite scene is when we have the whole crew behind us, and Prodigy and I have on the Hennessy jerseys. I loved those shirts. Prodigy got them made." Havoc also commented: "The most challenging part of making the video was staying awake, because we shot non-stop from early that morning to 7am the next day."

While shooting the music video, Mobb Deep got into a fight with a man who was complaining about not getting enough screen time in the music video.
