One who stays on and/or near NO PARTICULAR river more than one lives in ones own house and spends long, strenuous hours enduring the rapids, with one's choice of various water sports, such as, but not limited to; kayaking, canoeing, rafting, and the ever popular tubing.
It is very possible that one has not showered in an extended period of time.
It is also highly possible to find among this wondrous group of people a body that smokes that beautiful, amazing, god-sent herb, marijuana<3.
1)
Person A: I haven't seen that person in at least a month.
Person B: Probably because that river rat never leaves the river.
2)
Person A: Man that person stinks.
Person B: You'll find that many river rats do due to an extended period of time on the river without a shower.
3)
Person A: Dude, what is that smell? It smells like... skunk!

Person B: Well see that river rat over there? First, it is not skunk you are smelling. Second, that is not oregano it's..... real good "TOBACCO" in that "TOBACCO pipe".
