When you have a cuckoo roll, it is when you have become obsessed with something. Cuckoo roll is your obsession. (Stranger Things, a song, that cute person down the street, saving the turtles, etc.)
OMG, CHARLIE, EXTERNALIZING YOUR INSECURITIES IS YOUR CUCKOO ROLL!!!
Yes Frank, I'm telling you, gardening is my new cuckoo roll. It makes me feel alive!!
