Stomping on the glass is a widely recognizable Jewish wedding tradition.
The groom stands to the left side of the Huppah, so he can stomp the glass with his right foot for the wedding guests to see. This abrupt shatter is met with cheers of “Mazel Tov,” an expression of congratulations and good fortune.
In reformed Jewish tradition, the bride and groom will kiss after he stomps on the glass. At Orthodox Jewish weddings, the bride and groom hug each other after the stomp, and guests will form a gleeful mob around the newlyweds.
There are several interpretations to explain why the groom breaks glass at the wedding ceremony. It is said that this tradition reminds everyone about the fragility of life and human relationships. Glass shattering is also a symbol of severing ties with childhood and the parental home.
