What little I can make out of Spanish and Portuguese, they jibber jabber about the same stuff we all do: sex, drugs/beer, rock and roll, crappy jobs, worse weather, and how amazing Shakira looks.
The English speaking peskies I've heard from the Gulf are pretty much the same. Insider gossip about jobs, chatter about family, griping about the weather. Like the Spanish and Portuguese peskies occasionally I'll hear them chatter with wives and girlfriends. It's never anything racy enough for TMZ or the National Enquirer. They know they're being heard worldwide so, unlike cell phone calls, they tend to avoid anything X-rated or illegal.
The Portuguese speaking peskies from Brazil are an odd bunch. They seem to include long distance truckers who alternative between jibber jabber and odd sing-song chanting to amuse and keep each other awake on the road.
