The disconnection of a telephone conversation caused by ones cheek inadvertantly pressing on the disconnect button. This is more likely to occur with touchscreen mobile phones.
I was in the middle of an important discussion when I experienced a cheek disconnect. This occurred when my cheek hit the disconnect button on my mobile phone ending my telephone call and my train of thought. Cheek disconnect can also lead to a unigab situation. (see; unigab)
