So many people around here say "Mom". Mam is common, but at least it British/English/Yorkshire/Barnsley common.
Low-key The young uns seem to use it differently. "I'm low-key tired" = "I'm a little bit tired" I cant remember ever using it in this way. And "a thing" "Is a working class Tory a thing?" = "Does a working class Tory exist?"
When people say 'this', as if the stated answer is the answer to end all answers on a given subject. Don't know why but it proper grates on me.
