yes you can call it 부산사투리.

and i don't know why you want to learn.

but it is not easy I am native korean and i have a girlfriend from Busan.

we've been together near 10 years

when I immitate 부산사투리 she always says that is totally wrong. and i think she doesn't understand every single 부산사투리 like 아저씨 아줌마's strong accent and old-fashioned words

so if you want to be a 부산사투리 speaker study it with native like actors do when they got a 부산사람 role in the movie or live longer there.
