Wow, these are hard to ID/source. Thanks for asking about them.
If you are wanting fanart of the actual people/characters in the images or as a Creator's Choice of Fandom template, I would say to use a brief description of the images and then if you request them, link the image in the additional details of your request. If you want actual fanart of these images (not using the meme as a template for another fandom) then please nominate them as separate fandoms along the lines of "Woman And Two Men Kissing Sequentially Photoset (Internet Meme)"/"MLM/WLW Simultaneous Shoulder Ride Kiss (Internet Meme)"; if you want people to draw their ships in that format, nominate them under CCOF as "Any Ship(s) as [insert description here]". You don't have to use those descriptions exactly but something around that length/specificity, and then include the link to the image in your request so people can reference it.
If you are wanting to request specific characters/relationships in these poses, that wouldn't be acceptable as an actual nominated tag since it's a little more elaborate than an appearance related AU, but you can include it as a prompt in the optional details of your request. In that case you could just link the images in your request, no need to describe!
Let me know if that makes sense. Also, if nominations close before you're able to nominate these yourself, let me know how/where you wanted them nominated and I would be happy to add them in.
