Saying for jerks, slackers, cocky bastards, arrogant pricks and very highly respected
douchebags meaning
you are the one cutting the slack, and nobody else. There isn't anyone else
in your life that you need to ask for help, because you know how to help yourself, and don't need anyone's permission.
"
Cut me some slack, Jack! Sorry, I cut my own slack"
"Did
your boss cut you some slack on your lunch so you can stay longer?
I am the boss, I cut my own slack!"
See jerk, douche, cocky, bastard, prick, asshole
