Today's BWOTD tends to be used in specific circumstances:
"It was quite a party and by 10pm everyone was getting pretty lairy"
'Lairy' = a person being loud and a bit in your face
As to the circumstances when this would be applicable, I would say 90% of the time it's when someone has had too many alcoholic bevvies (drinks). But you have to understand this is not a bad word, because most of Europe and especially England has a far greater drinking culture than here (an article on this following soon). It's just a fact and this is just a word used in relation to this, I will admit I've got more than a bit lairy on occasion myself!
These days the Graves Disease drugs have put an end to any lairiness on my part, but being a Brit' ya just never know when it might breakthrough my now more restrained persona! ;-)
