A few weeks ago I overheard a group of my male colleagues (including my boss) talking about me as they were walking back from a meeting. They didn’t see I was at my desk and I just heard the end of the conversation, they were basically asking my boss how I was doing health wise ( there is no issue here I’m very open about my health condition within my team) but then one of them said “ I’d like to see her drunk!” To which the others including my Boss just jeered in approval in a laddy way. As soon as they noticed me they looked embarrassed and changed the subject.
They obviously know I heard them but it was just so weird that I stupidly didn’t say anything. It’s now been playing on my mind and I don’t really understand why they would want to see me drunk or what it means?, is it a common phrase that other people use that actually means something that I’ve never heard before 
??
I’m probably overthinking things but would just like to understand what it means 
. For context I’ve known most of them almost a decade and we normally chat about all sorts and are all really friendly. Just want to understand so if needs be I can give them a bollocking!!
