underground boombox 

the act of beatboxing into a woman's vagina during cunnilingus in order to give her pleasure some rhythm.

I gave her an underground boombox when i went down on her so that even if I wasn't that good, she could at least enjoy a catchy beat.

Secret Underground Rave Party 

Secret Underground Rave Parties are the best parties to have. They are underground somewhere, usually have techno, glowsticks, & alcohol involved. Since these parties are awesome & secretative, you must be on the list, know someone there, or be cool. Usually there might be a couple rockstars involved doing cocaine in the back.

Guy: Hey, you want to go to a Secret Underground Rave Party with my Friday night?
Girl: Uhh, you got invited?
Guy: I'm bringing glow sticks.
Girl: Ah.
