Memes are those familiar images with humorous captions.
This random meme generator uses some sort of computer hocus-pocus (ai, if you must) to generate phrases in the forms usually associated with the meme’s base image.
There are nearly fifty base images on the web based version.
The results can seem odd (or rude) but if you keep clicking away something will turn up that’s relevant to your mood.
Seriously though, “Beware, no profanity filtering was done on the training data so you may encounter vulgarity.”
And you’ve probably got time on your hands.
