I’ve been watching Derry Girls on Netflix, which is very funny, but a little crude.
There’s an episode at a wedding where everyone is mad to participate in “rock the boat,” which is a kind of seated line dance. I was sure they had invented it as a joke for the show, but it’s a real thing.
And in case you were wondering, Derry Girls didn’t invent it, they just brought it to the rest of the world.
As with most wedding / line dance things, it’s very silly.
