"She dips beneath lasers" is an expression meaning a woman has entranced you with her sultry beauty.
"She Dips Beneath Lasers" is the eerily haunting tune sung by Adam in the first season episode, "Office Campout" in the television series Workaholics. The song refers to the virtuous acting in "...Entrapment, the Catherine Zeta Jones movie. It's a classic." The end of the episode shows Adam, along with Blake, Anders, and the two techies (whom the guys had thought were robbers) using psychotropic mushrooms, and singing the song in the dark office with hundreds of glow stars attached to the ceiling, with rather warm harmony.
