I believe we Brits are called Roast Beef by the French. Its funny. I'm not offended. I dont look for excuses to call someone racist like you do Robert Dazzulere. You must be a nightmare to work with, just incase someone says a wrong word or mentions something that sets your antennae twitching.
I have never heard or been aware of any French person referring to English as 'rosbifs'.
The only time I have heard the word is when an English person makes the allegation about the French using it.
It is apparently, a term used for English, not for British people. The French have a real affinity with Welsh, Scots and Irish people. There are of course a lot of Anglophiles in France, just as there are a lot of Francophiles in UK.
Others suggest that 'rosbifs' is a term of endearment and originates from an English liking for roast beef, which is hardly an insult. I much prefer an English version of beef to the usual French variety, only because it has been hung to allow it to 'season', whereas the French tend to serve their beef without the usual British three week seasoning. This does not apply to other varieties of meat such as pork, lamb, mutton, etc.
Indeed the French have adopted the term to refer to other roasted meats, such as in Alsace: "ross bif" which is roast horse meat, and more generally "rosbif de mouton", "rosbif au four", "la cuisson de rosbif", etc.
As you rightly said, it is a term not intended to be offensive.
Others suggest it is from an English song about roast beef.
However, longboat's description of French people was neither colloquial, customary or a recognised term and was absolutely intended to be offensive.
He openly admits it.
Nobody on this forum likes you, Robert.
Are you the self-appointed spokesperson for the forum?
Or just an opinionated person who believes his opinion must be the only allowed opinion?
welshblue isn't on my ignore list.
Then, obviously you failed to read or comprehend his/her post as you were unaware where the phrase 'mass convergence' came from.
Maybe you would have thought that it was a particular Welsh term, if you had.
