^^ very true maybe he could have said f'ing punk or called TM a little a-hole or something of the like, not necessarily anything racial but that language to me insinuates mal-intent when it's not said to a friend or buddy in a joking way, especially late at night with a stranger...just sayin since he said it on the phone he may have said it to TM since there is prior info of him saying it to begin with..
I'm just not 100% buying Zims story
he very well may have run up on him grabbed his shoulder like "hey you little ahole, the hell you doing out here in this neighborhood?!" Which to me, would be aggressive behavior and very directly leading to a potential fight. Just conjecture though since we'll never actually know for sure.
