6-7? No, my kid says it about a thousand time a day. Then, for some unknown reason they follow it with 41! WTF! I've shouted 42! many times and have tried to inform the child of the significant cultural and scientific importance of 42. Which, IIRC, factors to 2,3,7.

67 and 41 are the TikTok / Gen Z speech.

67 stands for «whatever», «I don't care», or, cyclically, 67!

41 is an expression of shock or disbelief – «that's wild», «no way» and stuff like that.

> 41!

That’s a very big number!
