thump_(meme) and fair_argument have starting to get confused.

https://e621.net/posts?tags=thump_(meme)+
According to the current wiki page for fair_argument "The act of someone winning an argument by presenting something, usually their tits." (https://e621.net/wiki_pages/53088). However there are posts tagged with fair_argument that lack any text or dialogue, see examples below:

The thump_(meme) has no wiki at present time, but seems to depict characters presenting their breasts with an onomatopoeia or sound effect (usually the word 'thump').
These tags are starting to get crossed with each other, see these posts https://e621.net/posts?tags=fair_argument_%28meme%29+thump_%28meme%29
There are also posts where the thump_(meme) could apply (at least in theory) but isn't added, but fair_argument is applied, see below:

Also posts where there is no sound effect or onomatopoeia or dialogue but the physical action the two tags often depict is performed, see below:

I don't know how to resolve this so I'm posting this observation to the community.
In my opinion, the wiki pages need clearing up to either distinguish these two tags. The thump_(meme) could be set apart to denote the specific depiction of a sound_effect with the action and fair_argument could be defined for posts with dialogue or some depiction of a conservation. Although the physical act itself might be the meme at this point, so a tag alias could work. Not so sure about the alias idea, since having these two tags might be more useful for specificity. At the same time, thump_(meme) could be totally unnecessary since applying breast_drop and the proper sound tag could work. But the posts with thump_(meme) do have a very specific pattern to them which could need its own distinguishing tag. Thoughts?
