1.
cob
bad mood
"He had a right cob on" -- translates: "He was in a bad mood"

This was current in the UK's working-class east London/surrounding counties around 1950s & 60s. I haven't heard it used for many years.

It was always used in the sense of the example. I never heard it used as a verb or adjective
