Feel the burn

Mad at my ex I did the ultimate BURN!!!

He has a tracfone which cost to send and receive text messages. So after he had been verbally abusive and on the verge of physically abusive, I sent him a text message. F then the send key. U then the send key C then the send key K then the send key. YOU then the sent key.
That was about 3 minutes used up. He sent me back stop using my minutes.
No im sorry I thought okay. How bout this.
"How many minutes do u have," then the send key.
"17 now" he texted.
" How many now" I texted.
16.5
How many now? then the send key.
" Your an A**" send key.
How many now? How many now send key.
How many minutes now? Send key.
"stop sending my messages" He texted.
" Burn how many now" send key
He eventually quit reading the text messages but he read quite a few of them.

So tell me about your best burn.
