Cover art for Sex And Candy lyrics by Marcy Playground

I had to add my two cents. I think that perhaps it's about a woman seducing the speaker. I haven't seen the video, but this song just seems to sexy to be about much of anything else.

So think about it. He's by himself, he looks up there's this very attractive woman trying to seduce him, he gives in, he's exstatic, but doesn't know her, (who's that lounging in my chair, casting devious stares) and frankly can't believe that she's going to have sex with him. (Mama, surely this is a dream, must be my dream)

Pretty simple, eh? No need to overanylize this one.
