A mate of honour is the male equivalent to the classical maid of honour. The bride will often choose to forego the common maid of honour-bridesmaid combo for a less conventional male 'mate of honour' due to a lack of close female friends or an unbreakable bond with her male best friend. The 'mate of honour' will have responsibilities similar to that of a maid of honour including: planning of the infamous hen party, bridal shower and the obligatory catching of the bouquet. The 'mate of honour' signifies clear progress in the battle towards gender equality in all areas of life.
Tova: Joe, will you be my mate of honour to avoid a potential massacre amongst my female friends, and of course because I love you dearly?
Joe: I would be honoured to, what colour dress should I wear?
