Most women expect flowers, a candleit dinner or a bottle of expensive champagne when their man proposes to them. But this guy decided to dazzle his girlfriend with a bucket of green goo.

The proposal, which was all caught on video, shows fiance John preparing a bucket of green gooey substance that is then dumped all over his fiancee Nikki in cruel, prank-ish fashion.

As Nikki marches around angry and covered in goo, John pops out an engagement ring. She doesn’t believe him at first, but he assures her “it’s a real diamond.” And surprisingly, she says yes!
