The black haired girl's name is Celina, the red-haired girl's name is Alina (Celina often calls her "Egg"), they are sisters and play to be pregnant in this video, a third girl is filming and all are speaking youth slang.
Celina (09:19): Alina wants to show you something, guys.
Alina (09:22): Actually, I don't know how to do that. My doctor only put it in once.
Celina (09:26): And of course she didn't pay attention.
Alina (09:29): Eh? I did! Namely it is such a replacement brace.
Celina (09:32): Alina would actually have had something drilled into up there. Into her gums.
Alina (09:37): Screws.
Celina (09:38): With screws and so. But - she was afraid of it and that's why her doctor gave her this and said "If you want you can wear this at home". And Egg thinks that because he said "if you want" she doesn't have to wear it.
Alina (09:48): He said "if you want".
Celina (09:50): He actually said that. But she wears it of course because otherwise I really call there on Monday and say "Ey, she doesn't wear this, ..."
Alina (09:55): But I also do not know at all...
Celina (09:56): "... drill this into her".
Celina (09:57): Come on, I'll try, I know exactly ...
Alina (09:59): You don't even know where the clips are.
Celina (10:00): I saw Tiktok!
Alina (10:02): Oh God! Dude, you're not a doctor! You can't at all...
Celina (10:03): Come here!
Celina (10:04): Inside!
Celina (10:08): And now...
Camera girl (10:09): Oh my god, Egg looks like a planet.
Celina (10:10): Now, how do I do this?
Camera girl (10:11): Egg, this looks so bad!
Alina (10:12): Yes, therefore it is intended for home use only.
Celina (10:18): Boy, stop pushing that out with your tongue.
Alina (10:19): I have not done.
Celina (10:20): I am very pregnant, do not provoke me.
Alina (10:22): Stop that, Cel!
Celina (10:23): I put it in again anyway.
Alina (10:26): That's a whole new level of brace. I look like a planet.
Celina (10:45): I got myself such ...
Alina (10:46): What? I am supposed to eat with this thing?
Celina (10:47): Yes. I got myself such wasabi peanut crunch crispies.
Celina (10:56): Now here, Egg, taste this one.
Alina (10:58): How should I eat something?
Camera girl (10:59): This triggers contractions.
Celina (11:00): Good!
Alina (11:07): Ey, you can hang something here, hang a key here.
Camera girl (11:10): Laundry or so.
Celina (11:12): We hang a key here and you'll never forget it again.
Alina (11:14): I swear.
Celina (11:16): I'm going to take a wide stance. Stephane, come!
Alina (11:19): You're still in sixth ...
Alina (11:22): Ew, pickles water... So I try a pickle now. With Nutella. I actually don't like this.
Camera girl (11:28): Egg, if you want to remove your make-up, how do you do this?
Alina (11:32): God, what is running out? That's my bladder! Oh god! Stephane! Help me!
Celina (11:38): What is running out?
Alina (11:40): I don't know! I haven't yet...
Celina (11:43): You said Stephane, girl!
Celina (11:45): Now eat... Don't put your whole hand in the nutella, man.
Alina (11:49): How shall I eat that?
Celina (11:50): Your front teeth aren't impaired!
Celina (11:52): If you want to see a video about the brace, feel free to write a comment, write "#Zahnspange".
Alina (11:56): Man, it was such a mistake that I showed you this, dude. If only i had just thrown it away, like all my treatment options.
