Okay, since you begged sort-a.

When I got frustrated with my computer or whatever around the turn of the century 2001 rather than verbalize it with an expletive, I did the following instead.

I'd clench my fists and upper body and make a sound of frustration and mild irritation. We called Kaden, who was about 2 years old, Chunky, because he looked like a miniature football player.

He would clench his little fists, squish up his face and shout: "De, De, Deet." And everyone laughed and applauded. I was amused and embarrassed, simultaneously.
