The novel revolves around the mishaps of its narrator, Fred Trumper, a floundering late-twenty-something graduate student with serious commitment and honesty issues that earn him the nickname "Bogus."
It follows a non-linear narrative in the form of a sort of "confession" authored by Trumper, who humorously recounts his various failures in life and love, from his New England childhood through his experiences on foreign study in Vienna, Austria, and as a graduate student in Iowa, leading up to the present-action setting, early-1970s New York, where Trumper is attempting to sever himself from his adolescent past.
The title refers to a method prescribed to Trumper for the treatment of non-specific urological disorders relating to his abnormally narrow urinary tract.
Trumper's urologist, Dr. Jean Claude Vigneron, offers him three options for the treatment of his disorder: abstinence from sex and alcohol, a painful operation to widen the urinary canal, or the Water Method, which consists simply of consuming abnormal quantities of water before and after sex to flush bacteria out of the urinary tract.
Trumper is a graduate student at the University of Iowa in comparative literature whose thesis is to be a translation of an ancient, "Old Low Norse" epic called "Akthelt and Gunnel".
