Is that normal ? or it's kind of duckass ?

I too am curious to know exactly what it is and how it affects day to day life. I've seen a lot here about how to relieve it and tips to avoid it but no clear definition. From what I just googled it's when the lower spine curves more than it should?

Here's a video explaining it. It's in Spanish, but the diagrams are very self-explanatory if you don't understand it. https://www.youtube.com/watch?v=9pPY2g7fQlU

At around the 7:40 mark, it shows all the muscles involved.  You'll see that the muscles attached to the front of the pelvis attach to the femur.  So as you lengthen the femur those muscles tighten, pulling on the front of the pelvis and rotating it downward, causing your lower back to curve outward and making your butt stick out, aka "duck ass".

Isnt that terrible? from the pictures alone how could that possibly be reverted? Certainly not through exercises..

Excercises might help, but it always will fix itself with time as the muscles adapt. Apo posted a time lapse of his lumbar lordosis going away.
