First off, this is primarily about women.
Thus, and because it is much more polite and kid-friendly, and more accurate, I strongly encourage traditional phrases involving guts. It is guts which go squirrelly when things get scary. Not men parts.
(Off my soapbox!)
I agree with you. So funny that men say they want women to be feminine, but to “grow a pair.”
But with the under 30 group, it’s not just the women who are precious snowflakes. I had a guy who worked for me who had to take his back pack with personal journal and other “must haves” with him everywhere. I put a little aquarium with a betta fish on my desk, discovered he was deathly afraid of fish. When he needed to talk to me, he would stand in the door of my office, as far from the aquarium as he could get, so the fish “wouldn’t jump out and attack” him. He had to take half a day off from work, because of a bug bite, not because he had an allergic reaction, but because he was so traumatized that a bug had crawled into his hat and bitten him, that he couldn’t focus on doing his job for the rest of the day. No, I’m not kidding.
