This is a song from Gwen Stefani's 2004 debut album Love.Angle.Music.Baby. The song is set back in the 1950's and talks about her going on a date with her boyfriend and losing her virginity. "Bubble Pop Electric", is the sexual metaphor.
The chorus goes "Tonight, I'm gonna give you all my love in the back seat....Bubble, Pop, Electric". (Back seat, being the back seat of her boyfriend's car, not her butthole.)
What society believes one direction is when in reality that are more than just the song “what makes you beautiful” and if you want proof go listen to “fool's gold” or maybe “end of the day” all by one direction
