I think for me is cucked_by_own_son

where_is_your_god_now?

That sounds like an anime title, "Cucked by my own son in a fantasy world with goblins and i have massive fucking knockers"

The fact that there's even a Peppa_Pig tag speaks for itself.

Subway_Surfers

This isn't really "funny" per se so much as it is absurd but I once found an upload of the full Axel in Harlem animation and a bunch of the tags were just adjectives followed by the N word

You_gonna_get_raped
You're_doing_it_wrong
What
WTF
Shitpost

There is a "funny" and "humor" tag, though one thing you will very quickly find is that a lot of people don't know how to be funny.

Rule 34. NO EXCEPTIONS.

One day we'll have the "ifunny" tag.

All of those sound utterly terrible.

Cruelty_squad simply because how absurd it is lol, and various among us tags as well. Also the "what" tag

'food_porn' the images are so goofy

this_happened_to_my_buddy_eric
Some guy commented on an image with this, and it got made into a tag

I had to look at it because... science?
The regrets... please bring holy water for my eyes
