skank request
A random friend request on a social networking site from a person one has no connection to whatsoever that is obviously from some sort of street person/prostitute/escort/stripper/other-equally-sad-person-with-Daddy-issues. Skank requests are a solicitation to "money for favors" arrangments or pornography.
Every time I log in on Facebook I'm assaulted with half a dozen new skank requests.
