squabble about (something)
To argue, bicker, or quarrel about something. Look, I don't want to squabble about the bill. I'm going to pay for dinner, and you can buy our drinks wherever we go next, OK? My parents were always squabbling about one thing or another, so no one was surprised when they finally got a divorce.
squabble about someone or something
to quarrel and disagree about someone or something. Please stop squabbling about Jeff, or I'll put him on my team so neither of you can have him. There is no need to squabble about the last piece of pie. There's more in the kitchen.
