A way of scumming a person out.
wow I thought Joe bought me a drink to be a nice guy, but now he asked me to buy him one! What a bronsan!
I just got bronsaned into working... I knew I shouldn't have picked up my phone
Bill: I tried to take a girl out on the date but Chuck insisted on coming.
Jake: Wow now thats a bronsan!
All that bronsan Ted does is brag how much money he has and he asked me for $35 to pay his phone bill...
