Old guy trolling SIL (short kinda) My SO and his sister had an office party and they had ton of drinks and LOTS of food. My SO and I took our time and we got there kind of late when everyone was already kind  of lit. When we sat down there was a MUCH older couple (70 maybe) and the gentleman was really wasted(this is important later). My SO's sister sat down with us and I'll call her vegapotamus(shes a vegetarian and she's about 5'2 and like 190) and we were given the option to order food and some drinks so I got a water and an app to share with my SO and my SO just got a drink. Well here comes vegapotamus and she gets this like cookie? with like this white cream in it and its covered in fudge and she also gets these little balls of flour that you stab with a syringe that comes in 3 flavors(one was cherry, chocolate and a vanilla one). Anyway so they bring them out and we're having fun and relaxing and when the food gets there this old dude starts mumbling something to his wife. When my SO's sister starts stuffing herself this old shitlord gets triggered and says very loudly in front of everyone "AREN'T YOU A LITTLE BIG TO BE EATING THAT???" It legit caught me off guard and I look over at my SO(who is also a shitlord) and he starts cracking up and all I can do is look at my phone and try not to bust out laughing. Vegapotamus looks horrified at us hoping we'd say something but my SO and I just keep ignoring her.This old dude keeps chugging whisky and  vegapotamus keeps shoveling sweets down her throat. After a about an hour or so the group decides they want pizza and they bring it out and vegapotamus takes two slices and old shitlord looks over and says "YEAH YOU SHOULDN'T BE EATING THAT". The old shitlords wife nudges him and tells him to shut up and Vegapotamus gets all red and immediately stops eating. My SO tries his best to not laugh and I can't even look up from my phone or I'd die laughing. Anyway the night winds down and we go home. The following week Vegapotamus brings the topic up to my SO and I while we were at his house. She said that when she got to work the following Monday she contacted her boss and tells her what the old shitlord had said which then her boss reaches out to the old guy and tells him he needs to apologize and that it was "rude" how he acted(DON'T WORRY SHE IS NOT HIS BOSS AND HE'S PRETTY HIGH UP AT THE COMPANY ANYWAY). The old shitlord walks up to Vegapotamus and says opss sorry you felt that way and walks off. Vegapotamus then tells us she said "Oh k thanks" in a "sarcastic" tone(whatever the fuck that means) and tried to act like it was nothing then SO says she's a little bitch for tattling and starts making fun of her for that which pissed her off and she fucked off.
