2. quite literally a shotgun prom. Male's parents force male to go with family friend/pathetic sympathy date in exchange for a shotgun for the male.
John: Do I really have to go to that prom? This girl is soo undesirable.

John: Sh*t! Fine I'll go. This is a total Shotgun Prom

I just left a shotgun biscuit in Tom's car, he is gonna taste that one.
An unhealthy relationship in which someone is hastily forced to be someone else’s friend. Much like a shotgun wedding where someone is forced to marry another person for alternative reasons and not true love, shotgun friendships usually involve guilt tripping or emotional blackmail.
