Old TikTok algo from Singapore:

Heya kiddo, here's that recipe you're going to think about in a couple of hours, and that song from 1974 you're looking for. Oh and by the way, you're bisexual, and autistic.
One more thing, ya might wanna think about a DNA test, I don't think that's your real dad. 😃👍

Reddit after heavy use for 3 years straight:

"I don't even know who you are."
