When you take time off of work, days, sometimes weeks, specifically for the purpose of sitting around jacking off.
I just paid for a subscription to this awesome porn site, and invested in a shit load of lotion and napkins. Now all I need to do is ask my boss for some time off so I can take a relaxing jacation.
A combination of the name Jack and the word Action; used mainly when describing the extremely violent, but also fucking awesome actions of Jack Bauer from the television program “24”. It is also acceptable for use when referencing Jack Shephard from ABC’S “Lost”, because he is also disgustingly bad ass.
Phil: Oh man you should’ve seen Jack, first he screamed at Locke and threatened to beat the shit out of him, then he murdered three people and then he topped it off by banging Kate.
