AITA for swallowing my friends entire coke packet?

I went to the bathroom earlier to snort coke w my friend and we entered the stall trying to put a line up on the toilet seat, the thing is the minute we were abt to snort it someone walked in and she jumped, she pushed my head and it went straight inside the toilet water, as if that wasn’t bad enough the coke started slipping off the sides and all did not want it to go to waste, so while she still held my head down I reached my tongue over and licked the whole thing into my mouth, once the person left me lifted me up and noticed me rubbing my gums, and asked where it went, I told her and she got mad at me and called me an asshole cokehead bitch

I don’t know why she’s mad and I’m concerned since she’s my plug, someone pls tell me aita?
