An intense conversation that is often one-sided and emotionally volatile that continues without stopping, crescendoing without a peak or end in sight.
A long conversation that ensues about politics, banking, illegal drug use, etc. - lead mainly by one individual who continues to beat the figurative horse to death until any others involved in the conversation wish they were elsewhere. Might be referred to after-the-fact as "There he goes, again. Had another Finder Moment."
