when a bum, stranger, acquaintance, etc. happens upon a young woman (the rushed) whilst she is using public transportation. he then proceeds to masterbate, ejaculate on her face (or the surrounding area, depending upon skill level), and flee the scene (i.e. rush). bumrushing normally occurs late at night, or in the wee hours of the morning. it is generally an enjoyable experience for the bum, but not so much for the rushed.
