interesting read and 66 posts already, wow.
specially interesting to read some "knowledge" of some who clearly never really lived in a dominican 'hood, evenif they may live in the country since years.
the first price of all jokes of course goes to Canadian Gringo again, we can't beat that "knowledge about everything", lol.
and then there is of course the large number of people who are dominicans or at least live in a real dominican neighbourhood/with dominican family or are married to a dominican spouse and raise kids, and they got it right.
in my surroundings, including my own family, the kiddies cal their father Papi, and quiet often the small boys are called Papi by their parents or other adults familiar with 'em.
adult males are often called Papi by same aged males and females, but usually by those who know each others well, it is less common between strangers.
when used outside of the father-children situation, the meaning of Papi depends on the specific situation and who calls it to whom.
when Rollout is sitting at a beach bar and a girl takes the next seat and tells him "hola Papi", then it sure has nothing to do with any bloodline relations(yet).
when Rollout is the next on turn at the supermarket or Colmado cashier, the girl at the cashier may say "venga Papi/dime Papi" to get his attention to tell him "it's your turn now", without any Barside intentions involved.
Papa and Mama i know only as the terms to call the grandparents.
i often realized the change from calling the own mother Mami to use then Mama when the females have own children, they teach their child to call Granny Mama and so do often they themselves, becoming the Mami themselves and turning the mother into Mama.
interesting topi, tho, it is something used/heard on daily bases many times, without ever thinking about it. i guess it's the way to learn a language other than in schoolclasses, such stuff comes automatiocally over the years.
