I don't know! I?m Dominican and I had no clue what "sirotet?" was. Yeah, mamey is common, but not the other one.
miesposo also does not know sioret?. in his defense he knows nothing about sport (i remember it to be a term related to boring ass baseball, right?). mamey he knows and uses.
few weeks ago i had to do translation work and when the conversation moved to sport i said that i was done because i don't know sport terms in any of the languages i use, not even in polish.
