Input: This happened a couple years or so ago, when I first met my mates girlfriend. The three of us were out with another mutual friend of ours, and we were all getting along well. We leave this club we're in and go to this small dinghy pub/club nearby. We chill there for a couple hours and at this point we're all pretty drunk. I get myself a fish bowl type drink that could quench the thirsts of a hundred gazelles. We're at a table and a few people join us who we don't know. I go to introduce myself, and inadvertently knock over a drink. Most goes on the floor but some goes on my mates girlfriend. I apologise and go to get some napkins. But before I do, in retaliation, she throws her drink on me, which was about a third full. Most of it hits my lap and she and my mate start laughing. So in my drunken state I feel i must retaliate further, so I pick up this fish bowl and pour the whole thing on her. This thing was so full she probably could've jumped in and swam about. 

So she's fucking drenched and I'm kinda laughing. She gets up and storms outside. My friend goes out after her. I get a text asking me to come meet them outside. When I get there, they're arguing with the bouncer. The bouncer wasn't letting them back in because she was too wet. I try bargaining with the bouncer but to no avail. I looked at them, shrugged and went back inside

Don't see them the rest of the night, but it was about half 2 so most places were closing soon anyway. Get a text the next morning saying I'm a cunt for pouring a drink on her and then leaving them.

So, AITA?
