The Telegraph is currently running a competition to find the most annoying phrases in the English language. Some great reader comments can be seen here.
My own Top Five are as follows:
1. Going Forward. Management jargon for "in the future." I hear this one approximately twice a day in my current workplace.
2. Winterval. Or in fact any so-called politically correct terminology that takes Christ out of Christmas (eg cards that say "Happy Holidays!")
3. Fresh Turmoil. A phrase that became somewhat over-used by my former profession, usually as a means of keeping a political row story going for another day.
4. With respect. Which, as everyone who has ever had this said to them knows, means with absolutely no respect at all.
5. Next station stop, when used by railway announcers. As opposed, of course, to stops that occur between stations due to leaves on the line etc.
