When you cheer yourself on for posting 2 Tweets with exactly 140 characters... you might have whiskey fingers.
When you comment on your brother's in-laws families post about Blackberry using the phrase "RIM job" and then giggle for a half hour straight, well - you probably have whiskey fingers. (Then forget to delete it, but luckily everyone involved finds it funny because RIM is doing so poorly on the market. Thankfully you read things while you're sober and have some small understanding of the tech industry.)
When you spend more than like 5 minutes adding some bullshit entry to Urban dictionary cause I don't fucking know why but I'm going for a smoke now.
I think I have whiskey fingers.
