The Wendy's equivalent of the notorious McDonald's Super-size for combo meals. For some small amount (usually 39 cents) more, you get more fries and a larger drink. Although I don't usually opt to Biggie-size, apparently Wendy's cashiers are required by company policy to ask everyone in a very obligatory sort of way whether customers would like to Biggie-size their order. Fortunately, sometimes you get a cashier who is sufficiently pissed off from getting angry or sarcastic replies to this question to not even bother you. I call such times "Good Times".
