please please

i wanna know the meaning of “naydaa” and “weyalalal” thanks…ur replied will be too much appreciated

A quick search on the forum could have led you to this explanation of Nayda provided some time ago:

So it means something like: It’s rocking.

W ya Lalla ya Lalla - Literally: Oh, m’am..
It can just be used as an exclamation. If someone is telling you a story, and then comes an exciting part: w ya lalla ya lalla, it was me who did it.
If that was actually the expression you meant. Otherwise, please provide a context.

Here’s my full explanation for “Lalla” if you 'd like to check it
