When one sprays whip cream into ones asshole then covers their penis ice cream, cherries, and hot fudge then preforms anal sex in their partner. Then one eats the Slutty Sunday.
Person 1: "Hey anyone up for desert"
Person 2: "I could go for a Sunday Slutty, you up for it Sarah"
Sarah: "oh, fuck yeah"

Person: *looks on desert menu*
Person: "I'll have one Slutty Sunday"
Waiter: "Excellent Choice, Sir"
