tony c - yes you are right, those words are used in general spanish as opposed to dominican. mind you, when others say "mi amor", perhaps they mean it.
i also know that a "pajero" is a mitsubishi montero, but "pajero" also means w*nker. i suspect you don?t know what a w*nker (*=a) is. someone else can explain it, if they wish - or do a search on the internet or something .
fuc? = a lot to do with bad luck, or jinx, or something like that.
cuero = a "sharon", tart, good-looking girl, especially if she's not wearing much clothing in public (i think).
zafacon = litter/rubbish bin, skip, etc.
chopo/chopa = not very nice way of describing anybody you don?t like, especially if lower class and/or uneducated.
cocotazo = a clout on the head
en olla = broke (no money)
taca?o = what my wife calls me when i don?t give her any money.
'ta pas?o = you are out of date, passed it, old-fashioned or something similar.
medio pollo = cup of coffee with some milk.
jugar al gallo y a la gallina = to have it off (fornicate)
i don?t know if they are all strictly dominican, but who gives a flying "gallo y gallina" anyway.
