(This is something that I wrote on askamanager.org.)
Handily Ofcom (the UK regulator for broadcasting) released the results of a survey on offensive language only last week. They asked people to rate various words as to whether they were Mild, Moderate or Strong.
They didn’t include the “Bugger off” or “F*** off” variants, but “Bugger” alone was rated as Mild, alongside words such as “Bitch”, “Cow” and “Pissed”. “Sod off” was also rated as Mild.
On the other hand “F***” was one of only two words in the General Swear Words category to be rated as “Strong” (the other being “M*****f*****”).
The entire report (a PDF) can be found here www.ofcom.org.uk/__data/…
