And someone explain this to those of us that may not understand

The person having their hair cut acts like a puppy… think furries, but with less costume.

(If wrong I’m prepared to be corrected.)

I thought it was something to do with dog years

That would actually be a fire punchline… but, knowing this instance, I’m gonna stick with my first explanation.

“You’re so mature for your age” is a line groomers often tell their victims as a way to explain why they’re interested in such a young partner.

I wanna be... groomed by mama hairdresser.

To this song, presumably.

Thanks for the explanation. I was so far off on my initial understanding.

naw. wow that's an aggressive e guitar.
