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.

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

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.

Nope!

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

Everyone has something that bothers them. As long as this is not expected to bother everyone or pushed on everyone that is fine. I also feel swear words are a bunch of BS.

It is assuredly not just you. I can't stand all those words ending in 'ummy,' either. Also, when people refer to an objectionable concept as 'icky' or 'gross.'. Let's use adult words, thanks.

Sounds yummy to me!

I don't often hear the word "yummy". I do, however, know someone who consistently calls an app an "ab", as in I just downloaded a new "ab" or my new phone has a lot of "abs". I don't know why, but it drives me nuts when he says things like this.

I agree and it does sound a bit childish. Perhaps it began with cooking shows like Rachel Ray...remember "Yum-O"? Maybe folks are too lazy about language to dig up words like savory, succulent and tantalizing to describe the food. The other possible explanation is they don't have the vocabulary.

bit like this 'cool' thing, to me if somethings 'cool' it's plain cold!

Yes. Men shouldnt use the word yummy. Its for kids

Yummy doesn't bother me, but I don't hear it very often.

Yum yum.....
