(noun.) experienced when one feels his phone vibrate in his pocket, pulls it out to check his new message, only to realize that he felt a phantom vibration and no one was actually trying to reach him. Bergasms are especially intensified when one is bored or feeling lonely and has a strong desire to talk to someone. When the bergasm is experienced, a state of euphoria consumes the desperate person only to end with an anti-climactic lack of a new text message.
