What do you think of me trying to get my mom to fulfill her chicken promise?
What is a "chicken promise"?
I have not effing idea what it is, but since she made a Chicken Promise, by gum, she should get her ass in gear and fulfill it. Otherwise, I plan to call a fowl on her.
It is okay to remind somebody of a promise they made, especially if it is something that you are looking forward to. It will not hurt anybody to remind and they might appreciate being reminded.
Will you guarantee the chicken?
Personally, a can't guarantee the chicken. I do understand where you're coming from. It sounds like you might be really really be hankering for some chicken. Maybe it was just some silly thing she was thinking of at the time. Maybe it would be best is just to forget about it. Or call a fowl on your mom.
