I got in a street fight  and won
Why were you fighting in a street fight? Are you okay?
I'm fine. He made fun of my shirt and I didn't want to take it.
There is no reason to fight anyone on the street. Do not let petty insults provoke you to such lengths.
I was just trying to defend my shirts honor.
That is no reason to get into a fight on the street. It is not that important that you had to fight someone because of your shirt. The other person could've had a weapon on them.
