To like someone; to stand with them, back them up; to really care for someone or maybe to even love the person. I think there may be many different ways to cut for someone.
I appreciate youdefending me against the haters, or giving me a place to stay/food, or jumping into the fight to defend me, or believ8ng in me - you cut for me, I cut for you.
The Australian saying “I didn’t come here for a haircut” is used to express that someone is there for a specific purpose and not to waste time. It’s often said in a straightforward or humorous way to emphasize that they expect action or results.
For example, if someone walks into a bar and orders a beer but the bartender is slow to serve, they might say, “Mate, I didn’t come here for a haircut.” In this case, it means they came for a drink, not to stand around waiting.
It’s similar to saying, “Let’s get on with it,” or “I’m here for business, not for small talk.”
