There is an American TV show named Full Frontal, hosted by Samantha Bee. It's kind of like many other comedy talk shows out there, such as the Tonight Show by Jimmy Fallon, or the Late Night Show by Stephen Colbert, etc.
I don't understand the show's name - Full Frontal, I mean, I know the meaning of each word on the dictionary, but the dictionary explanation doesn't make any sense. What is the actual meaning of it? Can anyone explain it? Thanks.
