Booth babe is slang for a female model who is hired for the duration of a trade show to attract potential customers. Such models are typically dressed provocatively and are hired for their appearance rather than for their knowledge about the product they are promoting.
A booth babe’s responsibilities typically involve greeting attendees, handing out literature and guiding potential customers to a sales representative. She may also pose for photographs with trade show visitors or take part in a short entertainment routine designed to gather a crowd.
In recent years, the label “booth babe” has picked up a negative connotation, primarily because some vendors have dressed their trade show models quite scantily -- in some cases exposing as much flesh as the law permits.
