"RangTang" is the name of a new vodka that's fused with orange and tangerine. But according to Urban Dictionary, it also has a very different meaning that I will decline to write here. The makers of RangTang maintain that they would have settled on a different name had they managed to find the Urban Dictionary entry with a Google search.
I've excerpted some other definitions from the online slang authority (the language is all Urban Dictionary's!) and put them in this quiz. Find out if you're keeping up with the kids better than the RangTang vodka company!
