The voicemail that results from drunk dialing. Often contains gibberish, cursing, music, random things, and occaisionally insults. Many times a drunkmail will contain 'Guess what?' followed by an equally stupid and pointless phrase.
"Duuuudddde, go watch Lord of the Rings. Your dad looks just like Theodan. It's cuh-razy! *pause* Peace..."
The next day:
"Hey, did you drunk dial me last night? Cause I think I got a drunkmail."
"Oh shit... What'd I say? I didn't say anything about Monica did I?"
