So I was out of town drinking with a couple of friends. One of my friends had a big brother who's a heavy drinker and we were staying at his place. The plan was to head downtown in the evening. We get to the place and right soon after he asks how many drinks we have on us. I tell him we have little bit of booze and a couple of beers. He then starts bashing us "what a little pussies/faggots" and I'm like cool whatever I don't drink if I don't want to.
As the night progresses he starts to get more in my face and tries to force me to drink with him. "come on man don't be such a pussy, come take few shots". I look him dead in the eye and tell him I know my limits and I'm cool with my own drinks. He then continues to pick on me with something like "Maybe we should go and wash your pussy in the bathroom" and I just A&A "as long as the soap is gynecologically tested for bacteriovaginosis" (I may have fucked that one up, really didn't know what to answer).
But basically everytime he spoke to me I focused on keeping the eye contact intensively and waiting for him to shy away. The picking went on and I didn't submit to his will and I saw him getting pissed about it. We then get to the taxi that was supposed to take us to the bar. In the taxi I'm having a laugh with one his friends and he tries to get my attention by grabbing my shoulder and saying my name, I just ignored him and continued with the other guy (focused on having fun).
When we get to the bar my friends brother is pretty fucking wasted and almost ready to go home. We are sitting at a table and I start to open up this random girl. Having a great conversation with her and both enjoying our time while my friend and his brother sit quietly next to me. When all the sudden my friends brother just out of nowhere pours a full drink on my head. Right at that moment I knew from reading RP that he was emotionally invested in me and he showed everyone that he's emotionally unstable so I just ignored it like it didn't happen. I said something like "god you're making me sweaty" and brushed my hair. Instant giggles from the girl.
My friends brother then got thrown out of bar later during the night from passing out.
I'm pretty new to RP and this was the first time I was being confronted by another male like that. Was it because he saw me as threat? Or because he saw me as a easy prey? Please critique my behavior and actions so I can reflect on this one better.
EDIT: Thanks for the feedback. I personally can't see how fighting someone clearly drunk in a nightclub would have helped my situation, if anything I would have been thrown out with him (what's there to win?). Student parties get wet and messy anyways.
I'm not interested in felony charges since I have a background in MMA. It's not like he was holding a frame there or confronting me, he literally just poured the drink and ran away, which I thought was extremely childish and not worth investing my time and effort.
Also I'm not sure if pouring a drink on someone would be concidered as an assault (and therefore legit reason to 'defend' myself by kicking the guy's face in) in where I'm from, maybe in 'murica.
