The bulk update request #15568 is pending approval.
create alias :q -> licking_lips
create alias :p -> tongue_out
mass update ;q -licking_lips -> licking_lips
None of these tags have any reason to exist; all they do is provide an inferior search to the tag combinations they describe.
:p's wiki states it's only for smiles and the emoticon itself depicts a closed mouth. However, it's not only used for smiles, nor is it only used for closed mouths. With all these differences in usage from user to user (most of which will have almost certainly not read the wiki), the only constant is that they're tagging tongue_out posts that probably aren't licking_lips. Speaking of...
:q's wiki is even more blatant about its uselessness. It describes proper usage as "running the tongue along the upper or lower lip in a "licking lips" sort of way", which makes it literally no different at all to licking_lips. I mean come on, it's not even specifically for licking the upper lip as illustrated by the emoticon itself. And once again, despite depicting a closed mouth it's also used for open mouths.
;p and ;q are just variants for winking (which I'm still annoyed we don't have a tag for, but that's a discussion for another topic). Simply add one_eye_closed to searches for the same functionality but with more results. Since they already imply tongue_out and one_eye_closed, I've submitted nukes for them as opposed to mass updates.
tl;dr: All four of these tags are pointless when users can just search for combinations of tongue_out/licking_lips, closed_mouth/open_mouth, smile, and one_eye_closed.
