Dude-fussing is when you go camping and someone feels a primal need to poke at the fire every 30 seconds, or when someone is barbecuing and they can't just leave the burgers alone.

Dude-fussing说的是这样的几种行为：出去露营的时候，有人差不多每隔30秒就要捅捅火堆，或者，出去烧烤的时候，总有人不停翻转烤架上的汉堡。这其实就是我们说的“瞎捣鼓”。

These actions don't have any real effect. But they are fussy and make a great show of effort at doing something to make it all better.

他们这些瞎捣鼓的行为并没有任何实际效用。他们只是喜欢瞎忙，很想表现出在努力做好某件事的样子。
