I was going to ask if Jackethammer was thinking about forced_rape or mutual_rape. "Rape" is regarded as unconsented sexual intercourse, "forced" as being made to do other sexual acts (oral etc.) against the victim's will. Just unwanted touching of the victim is "molestation". Forced_rape for when characters are made to have sex with each other against their will. Mutual_rape is when each of the characters is attempting to rape the other at the same time. (Or I think that's how it goes.)

Should be redundant with "cum_inside", right?.

you_gonna_get_eaten ... Ok, I admit I've used this without really knowing if it is subjective. Thoughts?

Replace or alias it with vore? Or keep it separate to define vore that is ABOUT to happen.

So then, what's the difference between this
gelbooru.com/index.php?page=post&s=view&id=1145247
and this
gelbooru.com/index.php?page=post&s=view&id=1030046

or perhaps this
gelbooru.com/index.php?page=post&s=view&id=1141268
and this
gelbooru.com/index.php?page=post&s=view&id=1033963

many have both like
gelbooru.com/index.php?page=post&s=view&id=1129566
and
gelbooru.com/index.php?page=post&s=view&id=1139032

I understand it's subjective which is why I listed it here for clarification. Shall I just leave it all alone?

Alternatively, forced could be used for just general situations, rape could be used for people being forced into sexual acts.

This does not answer your question(Because I'm not sure just what an image has to meet to be tagged as rape), but I'll just tell you what I'd tag the images you listed:
First two I would probably tag rape.

1141268 - doesn't come off as rape to me.
1033963 - wat

1129566 - I'd call that rape.
1139032 - That expression could be shock over the sudden Gentleman's Mayonnaise in her mouth. I'm not sure about that one.

I destroyed cute's attempted revival, and kurogane mk2 tried to bring futa_is_always_bigger back.

Also it's been doofy1 trying to bring big_Breasts back. it's almost up to 2 pages again.

it's practially tag vandalism since he's been spamming the same tags on half the pictures there.

[edit]

It should work fine if it's saved for cases where someone is in plausible danger of being eaten, but it's not actually happening yet, and it's fairly unambiguous that eating is what's going to occur.

I put it on post #928357 because in that artist's pictures, Kyuuki is ALWAYS trying to cook somebody for lunch. She leads on Imoge at one point, and then puts her in a pot.

The Mystia and Yuyuko ones (e.g. post #867783) should count because it's a running joke that, whatever else is going to happen to Mystia, Yuyuko is also going to consume her flesh as nutritive material...

post #866769 is more like vore because the lunch is already in the predator's grasp and covered with saliva.

post #826012 post #785217 post #724601 I don't think have enough association with eating. Flandre also eats people, but often she just looks at you like that.

post #434856 IDK. They could just be planning to drive the smaller dog out of their territory.

The rest look fine...
It's better than you_gonna_get_raped being used as a catch-all, which is what people were doing before.

Danbooru has some "after_fellatio" tag. I wonder if we even need that, with cum_in_mouth, cum_string, etc.

Sounds useless to me. Just like applying the aftersex tag with the cum_inside tag.

Unless you are using one as a verb and the other as a noun... In which case you could create separate tags... but it isn't a must-have.

lol applying grammar to sex... I've never felt like such a FOREVER ALONE.
