it is a formal, old-fashioned word這是個正式、有點過時的字， and in ordinary conversation people simply say日常對話裡大家就直接說 annoying or troublesomeannoying或troublesome。 notice that it usually points at a thing or a situation注意它通常是指一件事或一個情況， not at how a person feels而不是人的感受： a person is vexed人會vexed感到惱怒， but the thing that did it is vexatious但造成這種感受的東西才是vexatious。

Its most alive use today is in law, and if you meet the word in the news it is almost certainly this one. A vexatious claim, a vexatious lawsuit, or a vexatious complaint is one brought without a real case, on purpose, to trouble, embarrass, or exhaust the other side — usually because the person bringing it has money or time and hopes the other side does not. A court can declare someone a 'vexatious litigant', which means they have filed so many pointless cases that they must now get permission before filing another. There is a matching phrase for freedom-of-information requests: an office may refuse a request as vexatious if it is really meant to harass rather than to learn something.
