A Walking Minefield

A person who is essentially unstable. You never know what will randomly trigger an episode of rage from them. Anything from a joke, to a random topic or even just existing as a friend to them may be enough to randomly set them off. People who become long term friends with walking minefields will learn them like an old game of mine sweeper, but will always get exploded due to the being close factor. Walking minefields will use the most personal, hurtful, insane attacks against their friends when this random/unwarranted mine shows up.

I cant be friends with someone that's a walking minefield where if you say the wrong thing they yell at you and block you instead of talking it out. Like how was I supposed to know I'm not allowed to talk about cookies because ur dad died from choking on a cookie??
