Pretty confident it’s from South Park: https://en.m.wikipedia.org/wiki/Goobacks

If I’m wrong I’ll accept that. If I’m right nope we learned a valuable lesson about making the worst assumptions about strangers in the internet.

I identified it as a South Park reference although the reference in question was parodying a country accent imo.

As someone who grew up in the country however, fuck em

Ah yes, South Park, a TV show known for its sensitivity towards difficult topics. Quoting someone else being douchy just means you're douchy and unoriginal, it doesn't make you not a douche simply because someone else said it and you're copying them. You're still choosing to say those things.
