A person who used to be part of a tight river rat community but who has been banished because they took too many dumps where they shouldn’t have and wolfed down too much food belonging to others when they weren’t looking.
That river dog is a serious goner, he even tried to hump my girlfriend’s leg while wearing this weird, blank canine look!
