I did a little research to date these terms in their current tiktok usage, which i also had to look up because i'd never heard of either. I can't find anything at all before the late fall or winter of 2021 for face card. Ate seems to be a little more complex, I can find some similar uses in kpop stan twitter in 2019, but it doesn't seem to have breached containment until early 2022. I do see one urbandictionary entry from 2014 associating it to "texas slang," but I can't corroborate that on indexable social media so idk.

I think there's a really weird culture of rapidly-cycling terminology on social media, especially on TikTok where new words suddenly becomes hypervisible and mandatory. "You don't say Fanked? What are you, some kind of boomer? Your content will get no views unless you say Fanked now. It's been one of the most used words in the english language as long as you've lived and you don't say Fanked?" so now Fanked is a word you see a thousand times a day, and it just enters your lexicon and then fades away from view as new viral slang replaces it, so it becomes something that's "been around forever," even if by forever you mean like 3 months ago.
