OCSL - The act of silently dying inside because you’re laughing lik

The act of silently dying inside because you’re laughing like a maniac but your parent thinks you’re reading a book.

My mom thinks I’m studying, but I’m just laughing at my dog’s face.

I tried to fake reading but my brother knew I was OCSLing.

I was laughing so hard I fell off my chair, and my mom yelled at me.
