The singing is awful but it's not the worst part by a long shot.
In no particular order...
Girlhood instead of womanhood, you're not a girl, you're an adult man, it's creepy to talk about being a girl and associate with childhood
Simplistic, naive idea of what it takes to be a woman, as if walks of shame, prescription pills, overspending and bubble baths are what define women.
Dilly does not have a feminine bone in his body, it's giving pre pubescent grossness, even talking about being a wingman for twins is sexualising younger looking boys.
The dancing is awful, it's hardly Lady Gaga doing pokerface by the pool is it?
Oh and the singing is terrible too... Please tell me this won't be played on the radio...
