When in Trinidad or Tobago say "good day" or "good night" to everyone you encounter. Whether walking down the street; in a store; to workers; strangers; policemen; lifeguards - everyone.

When on the telephone; when you enter a room; when you ask for directions (always preface your question with a greeting).

If you don't feel comfortable saying "good day" & "good night", at least say "hi."

But never pass someone straight w/o acknowledging them, it is considered very rude & insultive.  

Let's "lime" or let's go "liming" means "hang out".  To "lime" is to casually engage in a social get together.

"Wine" on the other hand, like "wine de hips" is to turn your waist in a suggestive manner while dancing.
