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.
Back when I took singing lessons my teacher (who mostly taught kids but I was an adult learner) shared that she often had to veto the songs kids wanted to sing. One in particular that stuck with me was a less than 10 year old who wanted to sing Lady Gaga’s Love Game. Which has the lyric “I wanna take a ride on your disco stick” among other very adult lyrics.
Those lyrics are more spoken than sung, so for music lessons, that makes sense.
