n. An extremely unattractive woman who attempts to gain male attention by any means.
Originated from hookers in windows who were too ugly to attract patrons that they had to "tap" on the glass to get attention.
How was that party last night Jim?
It would have been fun Carl, but there was this tapper that wouldn't go away.
