In TL drow culture it's typical for the boys to dance for their brides on their wedding day. Usually the dance is choreographed to a specific song of the boy's choice so that he can add additional 'vows' or opinions/promises towards his bride. Their attire also is made to compliment the wedding band the wife gave them, which is worn around their necks, and are also usually more revealing than casual attire since it's for their bride's pleasure.
Once the dance is done, the bride's reaction tells the boy how much she liked it. Ranging from ignoring him, to picking him up and leaving the event, the reaction usually reflects how much the bride wants her groom. Therefore, while taking the groom away shows the highest praise towards him, it also means to the guests that they shouldn't bother either of them that night.
So, based on all that, this is hella far in the future when Azre and Mavis get married. |D Wys says she totally kidnaps him at the end, swooped up over the shoulder like a sack of potatoes, because that's the only way she ever carries him.
