Stealing the newlyweds' thunder is considered a terrible faux pas.
The picture, uploaded to Reddit this week by an unnamed user who has since deleted their account, has been viewed a staggering 1.36million times.
The picture shows a newlywed couple, yet to be identified, smiling as a guest gets down on one knee to present a visibly emotional woman with an engagement ring.
While the bride and groom appear to be happy with the events, the bride's arguably strained grin has been the subject of much discussion amongst Reddit commentators.
'Her smiles says "congratulations", her eyes say "that b**ch",' one user wrote.
'The bride is doing a really good job of hiding her murder,' another added.
I'm assuming the girl getting proposed to is her sister based off their bodies and similar face structures.
The bride doesn't look upset at all. Anyone that thinks this is purely basing their assumptions off of their own narcissistic and selfish feelings. Not everyone would get upset about such a thing. Not saying it's an OK thing to do, it's not, but it isn't the end of the world.
