Teenagers are still popping the question, but they're doing it in bigger and bolder ways that can sometimes rival a wedding proposal. Some ask on stadium Jumbotrons or surprise their future dates in class with giant signs. Known as a "promposal," they can pump up the overall cost of going to the prom. Teens then post videos and photos of their promposals on Instagram, Facebook, Twitter and other social media sites, fueling the trend.
"It's all about creating a post-able moment," said Dr. Kit Yarrow, a consumer psychologist and professor at Golden Gate University. "The more outlandish the promposal the more attention and feedback they get from friends on social media."
