[This episode first aired January 19th, 2008.] Does your family use a special word you've never heard anywhere else? A funny name for 'the heel of a loaf of bread,' perhaps, or for 'visiting relatives who won't leave.' In this week's episode, Martha and Grant discuss 'family words,' and Martha reveals the story behind her own family's secret word, 'fubby.' Why do we say that someone who's pregnant is 'knocked up'? The hit movie starring Katherine Heigl and Seth Rogen has a caller wondering about this term. A man whose last name is McCoy wants a definitive answer about the origin of the expression 'the real McCoy.' He's been told it comes from the name of turn-of-the-century boxing champ Kid McCoy. Is that really the case? A Michigander wants to know about the difference between 'titled' and 'entitled.' She'd assumed that a book is 'titled' Gone with The Wind and a person is 'entitled' to compensation for something. Grant and Martha explain it's a little more complicated than that. Quiz Guy Greg Pliska presents a quiz about 'False Plurals,' based on the old riddle: What plural word becomes singular when you put the letter 's' at the end of it? (Hint: Think of a brand of tennis racket, as well as the former name of a musical artist before he changed it back again.) Quick, which is faster? Something that happens 'instantly' or that happens 'instantaneously'? A caller wants to know if there's any difference between the two. A Brazilian has been researching why actors use the unlikely expression 'break a leg' to wish each other well before going on stage. He suspects it's a borrowing of a German phrase that means, 'May you break your neck and your leg,' but he's not sure. A caller who lived in the Bay Area during the 1960s remembers using the word 'loosecap' to describe someone who's 'not playing with a full deck.' He wonders if he and his friends are the only ones to use it, as in, 'Don't be such a loosecap!' This week's 'Slang This!' contestant tries to decipher the slang phrases 'dance at two weddings' and 'put the big pot in the little pot.' She also shares her own favorite slang terms for 'crumb crusher,' 'rug rat' and 'ankle biter.' By the way, you can read Grant's essay about slang terms for small children, 'Sprogs in a Poop Factory,' here. His column about language appears every two weeks in The Malaysia Star newspaper. A caller fears that the term 'Indian giver' is politically incorrect, and wants an alternative to teach her children. A Princeton University student wonders if his school can lay claim to being the first to apply the Latin word 'campus' to the grounds of an institution of higher learning.
