Russelling is the act of a guy moving in on a girl who his (supposed) mate has been trying to chat up. The "Russelling Potency Level" increases in correlation to; the effort put in by the first guy; the connection to the activities involved in the first effort and the the knowledge of these efforts by the second guy; how well the two guys know each other; and, how hot she is.

Not to be confused with rustling, which is usually used in reference to stealing horses, though it may be applicable if both guys are drunk and she fits the definition.
