I, I'm just not seeing the (incredibly obvious) metaphor.
When I first played this, I thought, "ho-hum, another surprise dance video." But the sheer explicitness (contains multiple f-bombs!) of this couple's movie homage soundtrack choice made me cringe. I wonder if their own respective mothers were expecting the line, "Imma execute every mothaf**king last one of you!" In their children's day of holy matrimony?
