Take a phrase or word from a song and replace it with something else. Like a ylyl kind of thing.
Lookin for love replaced with taking a dump
I was taking a dump in all the wrong places
Taking a dump in too many places
Searchin' her eyes, lookin' for traces
Of what I'm dreamin' of
Hoping to find a friend and a lover
I'll bless the day I discover,
You - taking a dump.
