Changing lyrics to songs to make fun of people you dislike
I have this habit of singing along to songs I listen to on my computer in my free time in the privacy of my home with no one else around. I always change the lyrics a bit, like inserting the name of an acquaintance from university whom I dislike. This acquaintance is very arrogant and attention-seeking. An example of this is that he loves to brag about research he did for a paper at Bachelor's level, as if that was something special.
For example, I will sing along to "Legendary Lovers" by Katy Perry, changing the lyrics from
"Legendary lovers, we should be legendary, la la la la la" to "Legendary lovers, they should be legendary, just like X's (his name) award-winning research."
Does anyone else have similar quirky habits? How normal is this kind of thing?
