A euphemism popular in the corporate world, signifying a person who spends the day furiously masturbating, pausing only occasionally to answer emails as quickly as possible to convince colleagues he/she is in fact hard at work on company matters.
Email autoreply:
'I'm working from home today, please direct any queries/calls to my colleagues. And don't call my mobile, I might be on the vinegar strokes then...'
Working from home sounds ideal, and there are some benefits; your commute is very short, you can sleep in later, you can work in casual clothes, or maybe even your birthday suit. But the downside is, you will be stuck in the house more, your social interaction with other people is reduced by a lot. Also, if your job is stressful or involves conflict, that will now be in your home. Makes it harder to separate home life from work life.
