A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The most popular seem to be lighthearted clever little truths, hidden in daily life.
Here are some examples to inspire your own showerthoughts:
If you made it this far, showerthoughts is accepting new mods. This community is generally tame so its not a lot of work, but having a few more mods would help reports get addressed a little sooner.
Whats it like to be a mod? Reports just show up as messages in your Lemmy inbox, and if a different mod has already addressed the report, the message goes away and you never worry about it.

A dog is a dog’s best friend
Goofy is actually a cow
No he isn't. He's a dog. But he has the hots for a cow
I hope you're not kink shaming.
Yo momma actually a cow
Or a landwhale
Are you calling Goofy a monkey?
Goofy is evolved, enlightened dog, who walk still-animal dog.
No you're cooking
