"Why am I so jacked" is used by males who work out or/ and li heavy weights to describe their muscles , or ideas they have a great build.

very strong, huge muscles

To pull a Jack is to shit on the top of a car then sit in it. Then hold your legs straight up as high up as they can go. Then to grab your toes. Then slide down the windshield screaming "AARRMAAGGEEDDOONN!!!!".

My mom was so pissed when I pulled a Jack on her new car...

Another feature that Apple has deemed unnecessary.

An absolutely amazing person with a great sense of humour. He will make you laugh until you are crying. He will always make you happy and will make you feel like you are invincible. Jack is always trustworthy and He is always the first person you will talk to about anything that's bothering you and He always sorts it out and makes the world seem alright; it doesn't matter how bad you are feeling he always cheers you up. He never fails to put a smile on your face. He will frustrate you when he says he isn't good enough because you know that it just isn't true and that he is just the best. Jack is good looking and is the type that is always In Good shape. He always wears the best outfits and looks amazing. His music taste is just incredible and he always knows how to lighten the mood. He is a kind, compassionate and caring person and even though he never sees that in himself he deserves to know that it is 100% true. He is just amazing.

All round good guy Jack, highly employable and has an abundance of that big dick energy to get them ladies to Niagara falls levels of moisture.

that guy who we'll never know if he hit the road
