A sexual act involving three dicks being inserted into three holes. While possible between humans, the act was designed for a kangaroo and three monkeys, as kangaroo females have three vaginas and monkeys are flexible.
Originated from Seussical the Musical, which features a kangaroo and three monkeys named the Wickershams battling some obvious sexual tension.
Whenever I'm out of town for business after I check into the hotel and put my stuff away I go down to the front desk and ask where the local wankershame blvd is.
