West Midlanders in their twenties have been branded "modern Vikings" because of their quest for sex, drugs and drink when abroad.
The Foreign Office has criticised the region's 16 to 30-year-old holidaymakers for being the most drug-crazed and sexually voracious in Britain.
Its report, entitled Project Holiday, reveals young West Midlanders are worst when it comes to wreaking havoc across the globe because they drink excessively, swim when drunk and have casual unprotected sex.
The 79-page document was commissioned to gain an insight into the mindset of young Brits abroad and cost the taxpayer £50,000.
The report's authors quizzed 1,000 young people for the report and found 29 per cent of West Midlands tourists thought a holiday was incomplete without a one-night stand, compared with a national average of 15 per cent.
Even more worryingly, 14 per cent of the region's holidaymakers did not intend to use contraception, compared with five per cent of the rest of the UK.
Some 43 per cent of West Midlanders in their twenties would swim while drunk, compared with a national average of 24 per cent.
And at least 21 per cent wanted to take drugs when abroad, compared with a national average of eight per cent.
Project Holiday also revealed West Midlands tourists were the country's least keen when it came to visiting cultural and historic sites. Just 18 per cent considered cultural attractions a priority, compared to 44 per cent of tourists of the same age from the South-west.
But Alan Dolan, a lecturer in social sciences at Warwick University, said it would be wrong to view the report's findings as a sign that West Midlanders and young people in Britain were worse than they had been years ago.
He said: "I think the opportunity is there for more young people to go abroad now because they have a greater level of expendable income.
" We are in danger of suggesting that young people are different to how they were 20 or 30 years ago. That's just not the case. Different opportunities have presented themselves to them.
"There is a lot of mileage in young people and I can't understand why those from the West Midlands would be any worse than those from other regions."
Brits abroad already have a loutish reputation particularly for their anti-social antics on Mediterranean resorts such as Faliraki in Greece, Ayia Napa in Cyprus and Ibiza in the Balearics.
The report suggests the UK's unenviable reputation could be further soiled as more holidaymakers can afford to travel overseas because of low-cost air fares.
It argues that Foreign Office officials should be better taught how to deal with the influx of hedonistic holidaymakers from the UK.
Ben Jones, an 18-year-old student from Birmingham, went with friends to Cyprus for his last holiday.
He said: "Most of the time my mates just drank and smoked weed. A few nights my mates got laid - they were single and away from everything.
"Holiday is like stepping out of the shadow; it's a release and there is no pressure."
