LOL...we've had something similar over here. Years ago, the word "bad" was used to mean something good thanks to folks like Michael Jackson and Mr T. Now the younger generation uses "sick" and "ridiculous" to describe something that is good. It can be hard to for an old redneck to keep up with. So I guess this means that I should hope that the spider that bit me was deadly, sick, ridiculous and bad. If it was then I should be fine. (fine meaning fine....not the opposite of fine)
Why would I do that, Roger?
What I will do is relate a story from a comedy gig I was at last night. Australian comedian Adam Hills was pointing out odd things that the Irish say (i.e. things that sound odd to people from elsewhere). One of these was the use of the word "deadly" to mean good, as in "I went out for a meal last night - it was deadly". Adam said that this causes problems when the Irish visit Australia and get told, "See that spider over there? It's deadly."
