A.M.

A.M. stands for “Annoying Mom”, who is usually very obnoxious, narssistic, irresponsible, loud, and simply unnecessary. An “A.M.” can be totally obsessed with her anti-aging skin products, cosmetics, clothes, accessories, as well as taking selfies of herself. (AND plastering then around the house)

A.M. makes unnecessary comments about people’s appearance to make herself feel better, and is also very focused on health and beauty.
Overall, an A.M. is a very unfortunate person to have as a parent. For those with A.M.’s out there, I am very sorry and also, move out ASAP.

Child: “My A.M. compared me to another “beautiful” person again.”

Friend: “Wow... I’m glad I have nice parents.”
