Can you define these popular missing words?
The act of instilling repetitive, catchy music/jingles into someone's head. Usually songs that you know will get stuck into someone's head like "Friday" by Rebecca Black or the Oscar Meyer jingle.
Someone instilling musical terrorism could do so by repeating the same verse of a song like Ke$ha's "throw some glitter make it rain" everytime glitter or rain is mentioned.
