the trend to end everything in the "-y" sound drive me batty. I mean nutty.

Nope!

Happyhiker, I use whatever word fits. If it is yummy I will use it. I have no problem with it. I use delicious and tasty also.

Depends on the context. The word itself doesn't bother me at all.

Try hearing its a ridiculous catch in CF, or better, its an unbelievable golf shot, when in actuality its on a golf course, lol.

It’s childish. I use it with my daughter, but she’s growing out of it.

I never thought about it but you are right. It is sort of childish. I have trouble with the word "bespoke" which is one of those words brought back from a century or two that just makes me think, "Yeah, that would be something way overpriced".

Can't say that I've said that since my daughter was young. when commenting on flavor I prefer to be more involved (how was it made, what was used in preparation) I tend to copy things I like.

Meh, I think tasty is dirtier then yummy. Yummy just feels childish.

Ok, it sounds childish and I don’t really use it except for ice cream which by its nature is, in fact, yummy.

Better "yummy" than the A word ... "amazing"

I say "yum!".

Yummy !!.... There, I said it ?

No! YUMMY, YUMMY, YUMMY. Not a word l use, but that felt pretty good. ☺

For the most part I don't mind it, unless it's being overused to describe things that aren't scrumptious or appetizing.
I sent a coworker a spreadsheet and some instructions once and his reply was "yummy." He meant that he liked the project and the instructions worked for him (yeah, I still don't get it). Without missing a beat, I responded, "If eating spreadsheets is your thing, I suppose you could print it out and eat it. Enjoy." He never used the word "yummy" when speaking with me again.
