No additions to offer, but thank you for introducing me to a word and a concept which were both new to me. Dictionary.com offers the following :

"Flytting

Flitting \Flitt"ing\, Flytting \Flytt"ing\, n. Contention; strife; scolding; specif., a kind of metrical contest between two persons, popular in Scotland in the 16th century. [Obs. or Scot.]

These ``flytings'' consisted of alternate torrents of sheer Billingsgate poured upon each other by the combatants. --Saintsbury."

Guest JoeF's use of the term suggests it may still be current somewhere in the world, examples, anyone?
