I'm wearing GG today as well!
I was the first proper scent I had. My big sister bought it for me for my 16th birthday (I'm 38 now). It reminds me of that exciting time, of exploring the pleasures of the adult world for the first time.
As for the powerful outlandish nature of GG? well it was 1984 when I first wore it. All the heavy metal heads at school took a bath in patchouli oil every morning. Me and my mates went out looking like Adam Sandler in the Wedding Singer. Believe me, GG was not loud for the time! Still love it.
