This scenario may happen to you, because fake slogan-bearing roaches are apparently being slipped beneath people's doors as part of a marketing campaign designed by Master Comunicacao, a Brazilian ad agency (as reported by AdArena). I don't know why the ad is in English if the agency is Brazilian.
Ironically enough, given this campaign, in the advertising industry consumers themselves are sometimes referred to as roaches. Thus 'roach baiting' refers to the practice of hiring cool-looking people to hang out in public and visibly use a product. The cool-looking person is supposed to serve as a trendsetter who influences roaches (i.e. the consumers) to follow his or her lead.
