lyricosis

the combining of two words:

lyric: “having a pleasing succession of sounds”

and
-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 b-tch 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.
