To do months of work within days, reject social invitations, and only leave the house to buy take-away because you must work hard to do well. Synonymous with IT certifications or playing computer games.
Sorry dude, I cant come out tonight. I've gotta no-life Cisco, as I've only got 5 days left to complete the last 6 exams of my certification.
Yea man, the only way your going to finish that work is by No-Lifing it.
To sit at home and play video/computer games all day.
Tomorrow I'm going to stay at home Nolifing WoW.
