look up any word, like sex:
The sincere and wholesome act of making a promise you never intend to keep even if you don’t realize it at the time.

From ‘abstinence pledges’ where creepy dads make their 8yo daughters swear in church that they will keep their virginity as a present for a future husband.
You: “Dude I promised grandma I would go and see her at the home for her birthday but then I spaced while playing Halo”

Friend: “You’re an ass”

You: “It was a total Abby, I swear”

is basically a backstabber and assumes people do stuff but they dont actually do it...oh and this person also smells like b.o. all the time no matter how many time he/she showers
an "abby" is also completely brainless, self-centered, stuck-up, and spoiled...and pigish
i walked by someone today and they accused me of kicking her dog...what an abby!!

i know pigs that smell better than abby
