"Nookie" is the first single released from the album Significant Other by Limp Bizkit. It is their second biggest hit behind Rollin' (Air Raid Vehicle).

One of the reasons lead singer Fred Durst attributes to the song becoming a success is that it's sung slower, and in a fashion where his lyrics are easier to understand, in contrast to Three Dollar Bill Y'all's rapcore style, where the lyrics in some songs are indistinguishable due to the fast screaming style Fred uses on the album.

The song is about Fred Durst's relationship with a past girlfriend, in which she used him for his money, and cheated on him with his friends, and yet he continued to stay with her despite the emotional distress this caused. The hook reveals his reason for staying in the relationship, which was because of the sex. "Hey, what the hell, what you want me to say?/ I won't lie, that I can't deny/ I did it all for the nookie"

In the song's music video, the band allowed hundreds of fans to participate, playing the song in front of the large crowd. All the men went to one side of the stage, and the women on the other side. When Durst sang the chorus, at certain parts he would hold out his microphone to the crowd, getting that particular side to sing. This was, according to Durst, to show that "guys go off hard, but girls go off even harder". The audio from this plays during the music video. At the end of the music video, Fred Durst is arrested for exposing his Limp Bizkit to the audience.

The song was memorably performed live on the first day of programming of MTV's "Isle of MTV", their summer 1999 promotion. At the conclusion of the song, Durst detonated a ship sitting out in the water a few hundred yards away.
