Would completing a 120v circuit kill you?

pending how long you completed the circuit for. for a second no, I did it by holding the prongs of an extension cord while plugging it in when I was a kid. Shocked the S*&^ out of me but did not stop my heart. But prolonged electrocution will eventually kill you, I would say a continuous 10 seconds to a min would do it. But I am not sure on the low number, just don't try.
