How do you Tie a Cherry Stem with your Tongue?

My friend showed me that she could tie a cherry stem with her Tongue. I've never heard of that, so I asked her how she could do it.

She wouldn't tell me for some reason or another; so I want to know how to, so I can show her that I can tie a cherry stem too.How do you Tie a Cherry Stem with your Tongue?
