An embarrassing public display of affection by your mother in print. Over the top written exclamation of praise that only a mother would proclaim telling you how great of a kid you are. (even if you are over 18) This could occur as a classified ad in the paper with a childhood photo, a facebook compliment, a myspace post or any other public note.
I was horrified when I opened my facebook and saw that she had mombombed me overnight with personal facts and over the top attempts at compliments "You are an amazing daughter!". **DELETE** ASAP
