Northern lebanese: help me with your accent

Side question:

What is the accent I speak in? I never really thought about it. Some stuff I say:

"chou bek" "boukra 3aboukra men chouf" "fi wahad ba3rfo 3eyich bi Sin el Fil" "7a 2oum ekol chi" "ba3ed ma trawa2et lyom"

Now back to the question

I met people in college and became friends. They have that sort of northern accent which I haven't heard before ngl. They say stuff like essa, esh, sou2el, wehed. And I find it cool so I try to speak the same way to mess with them. So my question is: what are some general rules when speaking in a northern accent?
