I'm old someone explain this to me please.

This whole thing where people are throwing their face into one inner elbow while the rest of that arm and the other entire arm is extended up and away from the body to the opposite side of the head is leaning into.

No I don't have a picture.

I've heard people say something like "look at my dad" "bitch now" or something lol. No idea what they're saying. I swear this isn't a troll post. I'm a confused person who's no longer in highschool.
