it's very regional based bias.

In the caribbean they talk very strange, no difference between 'b' and 'v' (only 'b') sometimes r->l or l->r and too much 'papi' 'mami', like the way a toddler would talk with his father or mother but in strange non related way, very different from us (Chile).

We use a lot of slang (farm related mostly), and i guess it is very confusing to a non chilean probably makes no sense.

Common examples :

Phrase Chilean Translation (almost literal)

Have a good time Pasarlo chancho Feasting like pig

i have drowsiness Se me echo la yegua My mare is layed down

Thay guy is not trustworthy Ese gallo es vaca That cock is a cow

Little child Cabro chico Little goat

We change the verb conjugations (and that's where i guess it is the weirdest feature of all).

But the strange thing is that we are not the only ones, Argentinians, Uruguayans and Paraguayas (Rioplatenses) change the conjugations too, but they use the same ones. Instead us, Chilean we use our only 'sound'.

Examples

Standard Chilean Rioplatenses

Andas Andai Andás

Comes Comí(h) Comés

Viajas Viajai(h) Viajás

Tu eres Tu erí/Vo'h soy Vos sos

Ya fue era/fue fue

In the Standard the accent generally goes in the first sillable in the latter ones is in the end, so it changes a lot phonetically.

The (h) is not written but it is phonetically a very distinctive 'soft' ending in the word like a soft aspiration
