What they meant:

What it really means:
Glam Slam:
Song:"Glam Slam is a song by American musician Prince, and the second single from his 1988 album, Lovesexy.[1] The song has sexual overtones with a spiritual undertone and fits the Lovesexy theme..."

Glam Slam - a sexual pun? I noticed this at UrbanDictionary.com: clam slam: A sexual act lesbians perform...
I'm fairly certain it borrows from "slam dance" and combines it with "glam/glamorous".
Isn't it short for "Glamorous Slamming"? or something?
