Nine out of 10 teenagers admit to being embarrassed by their parents, with dodgy dancing and public displays of affection top of the cringe list.
The survey polled 1,500 teenagers and 88% admitted to being regularly embarrassed by their parents.
Almost three-quarters (72%) said they would not introduce a new love interest to them in order to avoid embarrassment.
Researchers also questioned 1,500 parents for the survey which was commissioned by Twentieth Century Fox to celebrate the release of the Modern Family Season 2 box set.
They found almost two-thirds (60%) admitted to telling exaggerated stories about their own teenage days in a bid to impress their children.
More than a quarter (26%) admitted to telling their children they had received better exam results than they really did.
A similar number (24%) had falsely claimed to have seen classic bands such as The Beatles and The Who in concert
Relationship expert Jenni Trent Hughes said: "It's amazing the lengths parents will go to try and communicate with their kids but it would seem attempts at appearing cool and trendy are having the opposite effect and sending kids running to their bedrooms in embarrassment."
