After reading the translated lyrics, I am confused as to why some are offended by this. I think that this is expressing what a person thinks and feels when seeing someone attractive. Whether you are in your teens, 20s, 30s, etc; male or female; I think that anyone could relate to this.
I may be in my late 30s and married, but that doesn't stop me from turning around to look at someone who is attractive, or even fangirling over a hunky actor! (Chris Hemsworth is my fave!) I know my husband does the same thing. We ALL have hormones!! Even my 14yo daughter will say things like: "those abs", "epic nosebleed", and "that should be illegal".
Honestly, like others have said, these lyrics are pretty mild compared to some other songs out there! Whether the song is hip hop or rock, there are lyrics that are blatantly sexual. This song is just hormonal!
And that is the end of my opinion.
