Surprisingly it's missing.
Since cum_on_face is aliased to it I don't think it's intentional.

What about things like post #255129 and post #443851?
post #255129 yes
post #443851 Shinjidude forgot to remove the facial tag.
Does facial also apply to female_ejaculation?
Edit: @Hillside_Moose: I see nothing against this in the facial wiki.
@evazion: I would tag it cum if it were just the artist saying "it's cream", but not with an actual cake in the image

Re: post #443851
For sexually suggestive posts I think it's okay to tag what it's suggestive of. Technically it may not be cum, but for searching purposes it can be useful to tag it as such.
