"edit" daughter won't stop twerking

My daughter is 16 and she twerks all over the house. She thinks it's funny or something. She's twerking in front of the tv she gets on the table and twerks when me and my husband are relaxing. I spazz out on her and she's like sorry sorry and stops. Then she sneaks back out of her room and starts twerking in front of us while we're watching movies. My 5 year old is starting to copy her and then both come out and twerk around and then run back to their rooms.  My husbamd just busts up laughing. Idk if I should take it seriously or not, my daughter is annoying. But she's a teen and just being goofy. What do I do? Is this inappropriate?

Edit: oh wow I'm not gonna beat, whip, or hit my kid because she's being goofy god damn it's not that serious 😂 I'm just wondering if it's inappropriate or if it's just them being goofy. My husband said he doesn't care, that's why I asked.
