In horse racing, a Trifecta is a bet picking the first, second and third place horses in the proper order. It is extremely hard to get, so it pays out extremely well - something like a thousand to one odds.
In Motherhood, a Trifecta is something completely different.
Motherhood Trifecta: getting puked on, pooped on and peed on - all in the space of three hours.
Welcome to my world. I am now placing bets.
