Debauched stag dos are dying out because grooms fear their drunken antics will be posted online, researchers have found.
Almost a third of men in a survey said their biggest fear was of videos "getting out" afterwards and wrecking marriages, relationships and careers.
Camera phones and social media now mean embarrassing moments of excess can go viral in minutes.
The objectification of women at stag dos was is also worrying for modern men with 56 per cent of respondents saying they “hated“ it and were worried it could damage their relationships and careers if seen on social media.
As a result, 60 per cent of men now dread being invited to stag parties or holidays, 40 per cent turn down invites and 33 per cent hope the stag do tradition dies off.
Respondents to the survey believed embarrassing antics that were previously seen as harmless are now considered highly risky in the era of social media, with 18 per cent saying the prospect of being caught in "compromising photos" meant the traditional stag do was no longer "a laugh".
The research was carried out by travel experts The Big Domain, which asked 1,000 UK men about stage parties. "In the digital age a single lapse of judgement can be broadcast for the whole world to see, forever,” said marketing director James Starkey.
"Facebook and social media is playing a part in changing the traditional stag party culture because men fear the backlash they'd receive for their holiday antics.”
Party organisers are now reporting the rise of the "sten" party - joint parties for hens and stags - in a bid to put an end to the social media carnage.
