If y'all grew up in the '90s or earlier and you wanted to use your hand to pretend you're on the phone, you'd stick out your thumb and pinky and hold your hand up to your face to mimic a phone handset.
Well guess what, grandmaw? Today's kids have no idea why you're doing that.
There's a TikTok video going viral where a dad asks both of his kids what hand gesture they'd use to pretend they were on a phone call, and both of them held their palm up flat to the side of their head to mimic a smartphone.
At least they didn't say, "What's a phone call?"
The video has more than 275,000 likes already . . . and it's getting a lot of comments from adults who are VERY thrown by it.
