hagaloff
Hagaloff is when two people argue like they're trying to out-shout each other in a crowd. They don't care about the deal. They just want to be heard and make the other person look weak.
'You're not even worth the trouble. I could haggle a donkey into silence.'
'I'll take it for ten bucks. You're just mad I beat you at hagaloff.'
'You think you're smart? I could sell this to your grandma for half the price.'
