Butty with attitude - in Jamaica, a female "Tourist Official" asked, if I knew what "a wicked bumper" is: As I toll her I did not know, she explained that Jamaicans usually call a "butty with posture" , resp. "Butty with attitude" a
"Wicked bumper" - interesting: I did not know her expression, so far, nor did she know mine, and so we both agreed to use the other ones in the future...!
She wasn't going to tell people she was wicked natured, she knew that she was less likely to end up alone with a good natured facade. She also knew that not as many people trusted a wicked natured person, for good reason.
