allo guv, I do have to tell you that "jungle bunnies" is a term that was used when I was a kid, to describe black people, and it isnt a very polite thing to say....
it would be like me walking in some part of London or Manchester and calling people "hey you lot of wanking chavs..."
just a wee heads up that you might want to strike that one off your vocab while in the US or Canada.
The terms is still used and has made somewhat of a comeback during the last 3 1/2 years.
