jacked

1. 1
   adjectiveslang

   Physically strong, well muscled, or both.

   He came back from summer break completely jacked and ready for football season.

   Two jacked bouncers stood at the club door checking IDs.

   Similarripped, buff, muscular, brawny

   Oppositescrawny, puny

   Note

   Friends use it as praise, close in feel to ripped and shredded: wow, that guy is jacked! It grades like any adjective, so someone can be more jacked than last year or the most jacked person in the gym. In formal writing, muscular or powerfully built does the same job without the slang.

2. 2
   verb

   Simple past and past participle of jack.

   Two men jacked his car at a red light and drove off with his laptop inside.

   The airline jacked up its fares right before the holidays.

   Note

   One spelling serves as simple past (someone jacked my bike) and past participle (fares were jacked up before the holidays). With up it means raised, whether a car or a price; on its own, in casual speech, it can mean stolen. The form doubles as slang adjectives for a muscular build and something broken, so the sentence decides whether an action is meant.

3. 3
   adjectiveslang

   High from taking drugs or stimulants.

   By midnight half the band was jacked on pills and playing far too fast.

   Jacked on espresso, she finished the whole report before sunrise.

   Similarwired, high, buzzed

   Oppositesober

   Note

   The slang stretches from hard drugs to a strong cup of coffee. When the cause is named it follows with on, as in jacked on pills or jacked on caffeine. The word belongs to casual talk; in careful writing, high or overstimulated says the same thing without the slang.

4. 4
   adjectiveslang

   Broken, or flawed in some way.

   The printer has been jacked ever since someone forced the paper tray.

   My sleep has been jacked since the time change.

   Similarbroken, busted

   Note

   Its longer partner jacked up means the same and is just as informal, so a jacked printer and a jacked-up printer are equally out of order. The word reaches past machines to anything that has gone wrong, from a computer to a night's sleep. Among friends either works; at work or in writing, broken or faulty is the safer choice.
