gashcore
Music that is extremely unpleasant on the ears, causing intense displeasure and shouldn't be described as real music i.e. Nickleback. A portmanteau of the adjective British slang usage of gash, meaning something rubbish, worthless or very bad and the suffix "-core" derived from the word hardcore, used here to add extremism. It is satire of the overuse of -core to create new musical sub-genres.
"What on earth are you listening to? That music is gashcore mate! Put something better on."
"Don't let Joe pick the music, he'll put gashcore on"
