I think you’re confused why he brought up shaking anything at all, what you’re missing is that he brought up shaking an umbrella as a reply to the OP image that talks about shaking booty aka dancing.
The Finnish thing is that they don’t shake booty. The umbrella being the only thing they shake was just a way to highlight that they aren’t dancing like Colombians.
