We found another one this weekend that doesn't fit the acronym: In pain!
I tried to get DD's socks on, she wasn't having any of it, I was just as out of it as she was and forced them on, she said they didn't hurt (she said, in fact, that they were "too blue and too comfortable"), DH had Big Feelings and it all went pear-shaped in a bad bad way for a while. When I took the socks off (I had told her she could take them off and wear sandals when we got to our destination if they were still bothering her -- previously this has always solved her issue and we haven't needed to do it) I discovered she had a cracked toenail
So she was hungry, triggered (by having me force her socks on), and in pain; I was hungry and tired; DH was hungry and triggered (by hearing her scream). When we got to the quiet, fed point, we were all sane again.
But any pain will make you cranky.
