Ah, now that joke flew right over my head, I heard groovy and my mind instantly went to Austin Powers lol

I meant cheesy but like in a good and funny way, if that's what groovy means then yes. I sometimes get these words confused and have to refer to urban dictionary lol

I think it's generally conflated with nervous or insecure and used in the same contexts, hence the negative connotation. Self-conscious about one's body = insecure about one's body, though the words technically have different meanings I've often seen them used interchangeably in some contexts. I'm not a native speaker though so I might be wrong, this is just what I noticed people saying.

Yeah, I should've clarified I was mostly talking about deodorants, shower gels etc, because men do have some really nice perfumes. I personally prefer unisex perfumes as well, since I find women's perfumes too flowery and sweet, and I usually prefer woody, fresh scents. Basically I want to smell like the forest and some men's and unisex perfumes have achieved that, whereas women's not so much.
As for Fiji and charcoal, I don't actually know that one so I can't judge. My original comment was written a bit clumsily (in my defense I had just woken up and my brain wasn't functioning at full capacity) so allow me to rephrase: in my experience (ie. by smelling what my boyfriend has in his repertoire) a lot of men's stuff, particularly the stuff that's labeled as abstract concepts like "Cool Sport Rush" instead of a specific scent, often smells like toxic waste.
