you all talk about beiruti accent as if it's the normal accent!
ya3ne i think you've never heard a real beiruti accent in that case...
my father is from beirut, and when i visit the family...allah la ysame3kon! .. like eltellak becomes "oltoleeek", mtabbal becomes "mtobbeeel" ..to2obrineh.becomes something like to2brinaaa (actually the end is pronounced between the é and the a)...and of course the T is a very heavy T...it's like talking while eating!
my mother is southern, but since my maternal familly was born in beirut they speak 3ade...even my grandmother, she doesn't have a strong southern accent.. bass of course i love her "ya ti2ibrine ya sitti biddik a3mellek fraakeeh?"

just love it!
so i ended up with a weird accent! of course when i'm with friends i speak normally no accent involved..
but when i'm with my paternal family even though i keep my normal accent however i tend to say tawla instead of tawleh,,,swa2a instead of swe2a
when i'm with my maternal family i tend to speak using the "Shins" like lesh instead of leh... baddish instead of mabadeh...mafesh instead of mafi... et ainsi de suite
but i prefer the southern accent over the beiruti!!
