Today's creepy word gives you a pretty good indication of what marketers think of the average consumer. The term comes from roach bait, a poison that's sprayed in cockroach-infested areas. A cockroach eats the bait, returns to its nest, and excretes feces that are contaminated with the poison. The original roach dies, but other roaches eat the contaminated feces and the killing cycle continues.

Happily, some marketers are pushing a slightly nicer variation on this theme — brand bait:

"'Maybe only 15 kids are hit [by the Nintendo squad] at a birthday party but kids talk, a lot — at school, with SMS, by phone,' Ressler says. 'We know 15 kids can impact [on] 15,000 kids or 150,000 kids [through word of mouth]. You've heard of roach bait? Well, we call this brand bait. People have something to go back and talk to their friends about.'" —Natasha Bita, "Undercover agencies," The Australian, September 27, 2001
