I got Klappen = clap 
I didn’t watch further though. It’s like a flash card for learners to watch. 
Funny enough, Klapoen also means clap. It is another loosley related language, called Frisian. not often used, it’s spoken by @mattlock. I found the meaning while verifying Klappen’s meaning.
He was talking with @mirjam_465 about Frisian.
