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)
