What does it mean when a friend calls and says you dropped your phone?

When a friend calls and tells you that you dropped your phone, he means it as a joke.

This joke comes from a video. A father was holding his child. Suddenly he found that there was no child in the stroller, so he went to look for the child. In fact, the child was being held in his right hand.

I have also experienced this joke.

My friend Xiaomei called me once and said that she had dropped her phone.

I subconsciously used I went to dig into my pocket with my left hand, but didn’t take out my phone.

I was worried. Really, I couldn’t find my phone. Where did I drop it?

In fact, I hold my phone in my right hand and put it on my ear.
