Much like a bachelorette party is meant to celebrate a bride-to-be's last night of freedom, a momchelorette party is meant to be a last hurrah for the mom-to-be before the arrival of the baby. Usually thrown by the godmother or other close friend.
Example: "I'm pretty sure Amanda hooked up with that guy we met at Sandy's Momchelorette Party."
Example 2: "She may be 9 months pregnant, but that momchelorette sure can dance!"
noun. Title given to single females using online dating as a primary means of meeting potential future husbands. May also be used as part of a woman's professional dating title found on either her personal or professional business card, as in "The Ultimate Matchelorette."
"How many matchelorettes have you dated before meeting me?"--perhaps used during a face-to-face meeting with matchelor.
