-osis: "a disorder or abnormal state"
to mean when a person is singing and doesn't know or forgets the words to a song so they proceed to make up sounds and grunts to cover the fact that they sound like an idiot.
My sister and I got drunk last night and were singing Billy Jean loudly when I realized the bitch was suffering from lyricosis, she had no idea what the words were.
I love laughing at that dude that always sings for Karaoke even though he has such a severe case of lyricosis.
I don't care if I don't know the words to the song, a little lyricosis usually hides the mistakes.
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
