I'm just gonna say it. This meme is mid af. I think there just hasn't been good memes lately and people are starving for content. This is a C+/B- meme at best. Sorry if the truth hurts.
I think organic memes like this are better than ones designed specifically to be memes. That being said, yea, it's really not super funny/interesting/unique of a meme.
I think it's only a meme because the girl is attractive and has a southern accent. Take those 2 away and no one would give a shit. I think mostly the girl being attractive is driving the spread.
Knowyourmeme puts it well:
".....leading to memes, fancam edits and humorous romanticization from male internet users who found themselves attracted to her."
Well she either has a southern accent or she pretended to have one. But it definitely added to the "charm." I'd argue perhaps this video wouldn't be very popular if it wasn't a southern accent and a pretty lady.
