In my case I’ll say either Bloodhound Gang’s The Bad touch or Aqua’s Barbie Girl.
I mean… what the hell is “hanky panky”.
But for bonus points, I did also sing “take a walk on the wild side~” with no flying clue what “giving head” was supposed to be.
My dad was very irresponsible and taught me “Blind Man’s Penis” when I was a kid. Cue the looks of horror on everyone’s faces when I sang it out loud… not that I was totally unaware of why!
