I find the wording in the wiki cum_from_mouth confusing. (ie. is the tag only for explosive-cum from mouth???)
And i think the current wiki doesn't match the tag (the tag words cum_from_mouth just conveys cum from mouth).
(and other taggers seem to be using the tag for NON-explosive cum)

That wiki currently starts with :
"Cum from mouth should be used on images where a character has cum leaking, or exploding outward from their mouth, with the implication that the cum has either been vomited back up after being swallowed (due to excessive volume or similar), or that there has been so much cum deposited while engaging in anal penetration or vaginal penetration that it has completely filled the insides of the character, and is searching for an escape.

This is not to be confused with cum drool, which is where cum is oozing from the mouth in a non-explosive manner, and is the probable result of a messy blow job. Both cum drool and cum from mouth may be present in a single image, of course.
..."

The first paragraph is kinda ok (with the "leaking, or exploding") part,
but the 2nd paragraph seems to imply that cum_from_mouth is only for explosively large amounts of cum (from mouth).

***

cum_drool wiki is similar with "...ejactulate dripping from their mouth in a non-explosive manner. ...",
{ "ejactulate" is typo of "ejaculate" (Wikipedia ).}
and doesn't imply to cum_from_mouth,
thus seeming to reinforce a message that cum_from_mouth is only for explosive-cum (from mouth).

Other taggers seem to be use the cum_from_mouth tag for NONexplosive cum from mouth:
(looking through cum_from_mouth -cub)
(below doesn't seem to be explosive amount from mouth, in my opinion)
("borderline amount" is where i'm not sure if amount is explosive OR NON-explosive)

2) post #3999672 (cum starting around 1min 9seconds)(borderline amount of cum?)

(only got partway through the tag (27 posts out of 4943), a roomie wants to watch new Puss In Boots movie with me now)

If cum is coming out of a mouth it should get the cum_from_mouth tag. The wiki's specificity is nonsense. TWYS.

I think the cum_from_ tags are a bit supurfluous. The cum_in_ tags with leaking_cum covers the same use cases already. cum_drool also seems largely unnecessary with cum_in_mouth cum_leaking.

Do we have cum_explosion or something similar for that niche that this tag is failing to accomplish? It would probably be necessary.

cum_explosion makes me think of ignition though, which is a very funny mental image

Edit: apparently it exists but is not as intense as the examples of cum_from_mouth
