1. When you are trying to leave a message for someone and it just comes out awkward, dorky or stupid.
2. When you are trying to leave a message for someone and your phone drops the call.
I was leaving a message for my friend and I found myself rambling on and on... total voice fail.
A term used to describe Voicemail, sent or received, which has not been thought about before it is left and, therefore, results in a mess of irreversible word vomit.
"I had a message from someone but they forgot to say who it was. I hate getting Voicefail."
"I called that girl but I forgot to leave my number. I'm too embarrassed to call back after a Voicefail like that."
When you get a voicemail and the person leaving the message sounds like a cross between Milton from Office Space and a constipated cat. For a more simple definition, when the person who leaves you a voicemail sounds like a retard.
Dude, what's up with your mom? I rammed my cock down her throat then after I left she sent me a voicefail. You should take her to the hospital and get her larynx checked out or something.
