Input: This story is gonna sound pretty childish so let me give you guys some backstory.

I have a friend, let's call him Chris. Okay so Chris and I are both sophomores in college attending our local  community college in Northern California. (go Kings!) We have been friends since 8th grade and are both in a friend group that formed our freshman year of high school with 10 other guys. As we all graduated Chris, myself, and 3 other friends stayed and went to our community college, the other 7 went to Universities elsewhere. 

Throughout high school we all played basketball against each other at a park near my parents house (I now rent an apartment with 2 of my other friends who stayed back) and this past Wednesday two of our friends came back a few days early for spring break and Chris, myself, my 2 roommates, and the 2 that came back early decided to play at the park for old times sake. We used to use the ball at my house during high school but all my balls were so used and lumpy that they became unusable. Chris brought his ball that despite having a lump in it but it wasn't as bad as my old ones. We are all very competitive and during our last game I got frustrated after losing a close game and slammed the ball on the ground. The lump on the ball got a little bigger (still not as bad as my old balls) and Chris got really upset and wanted me to give him money for a new ball or buy one for him. I told him I wasn't going to buy him a new ball and he got upset at me and I gave him 4 reasons why I wasn't going to. 

1. There was already a lump

2. Back in high school and freshman year of college all of my friends, including him slammed my basketballs and messed with them and I never made them buy me a new one

3. He bought it at Walmart for $14.99 in October (I was there when he bought it) 

4. He still owed me $10 from a separate matter

He got angry and demanded I buy him a ball or venmo him $15 for a new ball. I told him I was sorry and it dumb of me to slam the ball but that shouldn't warrant me giving him money for a ball that already had a lump and was not very nice to begin with. I offered to just call it even on the basis that he owed me anyway but when I brought up the money he completely denied owing me anything.(I got my friends to back me up that he owed me)  I thought of it as a stupid argument and went back to the apartment. He has refused to talk to me since and even though I apologized and it is only $15 I feel like he is acting selfish. I offered to call it even on the money he owed me but he didn't accept it. AITAH for not giving him money for messing his basketball up a bit or is he overreacting? I know this a completely childish and silly post but here I am posting it anyway.
