Romance Scammer
Someone who targets an individual, usually through the internet and by phone, feigns feelings of love, then finds themselves in an impossible situation that requires money from the target.
Someone poses as an American, develops a romantic relationship, has a job overseas, then requests money from the target to get out of some unexpected disaster. Usually the money will eventually allow the scammer to be united with their target. See romancescams.org for a photo album of known romance scammers.
