Daniel Bickerdike left his partner Angie Schultz in little doubt that she won't be walking down the aisle any time soon after leaping from his seat to stop her catching the bouquet.
The hilarious video shows the moment he reaches to push the bunch of posies out of his pharmacist girfriend's hands at a wedding in Cape Town, South Africa.
The couple, from London, were at a relative's wedding when the incident was caught on camera.
They said they both laughed out loud after watching the footage, despite Angie not being amused at the time.
Area lettings manager Dan, 27, said: 'The video was taken at Angie's younger cousin Leanne's wedding to Larry Ball-Piatti."
"Angie was making a point of practising her bouquet catching skills so she'd be sure to catch it this time."
"However I managed to spot the bouquet in the corner of my eye and my natural man-like reactions stepped in allowing me make a cat-like interception."
"Although she was clearly a little shocked at first, we both found it hilarious watching the moment that was caught on camera."
The duo, who have been together for four years, said getting married had been a running joke because of their five-year age difference.
Daniel tells The Daily Mail that the dramatic reaction was just a joke and that though in the video Angie looks like she's going to rip his throat out and use it as a wedding veil, the couple laughed about it later.
