On this Tiger Woods-skewering track, Ludacris plays a helpless, frantic sex addict, rhyming about "sitting in this rehab class / trying to get myself unhooked on ass" over simple, percolating drums. It's the rap equivalent of a late-night monologue joke: good for a laugh, but nothing you‚ll keep coming back to.

“Like on 'Youth Knows No Pain' — we are the ones that should demonstrate, because we can take it,” Likke Li said. “We can pierce ourselves, take Ecstasy, dance all night and still go to work at our McDonald's jobs.” Despite the hedonistic sentiment in the song, the Swedish singer also admitted in hindsight her youth had repercussions. “I remember when I was 18-19 and feeling that I know it all,” Li said. “I always feel that I know it all. But that song is about realizing you don’t, and reflecting, ‘Boy, if I only knew what would follow.’”
