Ah, so we're at THIS stage of the boob trend now: Artists drawing anime/video game characters doing it.
All that's left is the comical flat-chested attempts, the fursona varieties, and the professional cosplayers performing this. Then it just cycles through all that until the NEXT boob trend. Rinse and repeat.

We've already had all three of those happen shortly after this meme started, with the flat chest and cosplayer examples even having stuff posted here.
