A Yabla subscriber has asked us to shed some light on the difference between noioso and annoiato. They are both adjectives and can be used to describe a person. There are some intricacies involved with these words, which we'll get to, but let's start out with the noun: la noia.
What a bore!

What is tricky about this noun (and its related adjectives) is that it can indeed imply boredom, but it can also mean "the bother" or "the nuisance." In fact, in the previous example, we don't know the context, but the meaning could also have been "what a nuisance," or "what a pain." The noun noia rarely refers to a person him- or herself, as "bore" would in English.
The following example is from Tuscany where noia is used a great deal to mean "bother." And it's often used with the verb dare (to give) — dare noia (to be a bother, to be annoying, to be in the way).
Erano alberi che davano noia e basta,
They were trees that were a bother and nothing more,

So che noia can mean "what boredom" or "what a pain!" And dare noia can be interpreted as bothering, or being a bother, or being in the way.
We also have the verb annoiare that does remind one of the verb "to annoy." Indeed, that is one of the meanings and comes from the Latin "inodiare" — avere in odio (to have hateful feelings for).
Mi disturba, mi annoia,
You're bothering me, you're annoying me,

But it is much more common for this verb to be used in its reflexive form annoiarsi. In this case it's always about being bored or possibly fed up.
Io non mi annoio mai quando sto con lui, mai.
I never get bored when I am with him, ever.Play Caption
We've seen that noia isn't just about boredom, so likewise, noioso can mean boring, but not necessarily. Let's look at some examples of the different nuances.
Noioso can describe a person who is not very interesting, a dull person:
Abbiamo solamente avuto un piccolo flirt.
We just had a little fling.
Genere depresso e noioso, capisci?
Depressed and boring type, you understand?

It can also describe a movie, for example:
Il film era noioso, purtroppo (the movie was boring, unfortunately).
Here's a perfect example of something that is not boring. It's annoying. And in fact, the N and O sounds can hint at that.
Eh, povero Dixi, il singhiozzo è noioso
Oh, poor Dixi, the hiccups are bothersome

Annoiato can be used as the past participle of annoiare, or more often, as we mentioned above, the past participle of the reflexive verb annoiarsi. In this case, it means "to get or to be bored."
Oppure: "No, non andrò alla festa di Marcello.
Or: "No, I won't go to Marcello's party.
Ci sono già stato l'anno scorso e mi sono annoiato".
I already went to it last year and I got bored."

But as often occurs, past participles are also used as adjectives. With annoiato, this can describe one's state of being.
Ciao. Sei annoiato o annoiata
Hi. Are you bored (m) or bored (f)
e ti vuoi divertire e rilassare?
and you want to have a good time and relax?

Let's try using all these forms in a silly, made-up dialogue.
Lei: Sembri annoiato, è così? (You seem bored. Are you?)
Lui: No, ho solo sonno (No, I'm just sleepy.) E inoltre, come posso annoiarmi ad ascoltare i tuoi racconti per l'ennesima volta? (And besides, how can I get bored listening to you tell your stories for the umteenth time?)
Lei: Beh, so che posso essere un po' noiosa a volte, scusami (Well, I know I can be a bit boring at times, sorry.) Allora smetto di darti noia, e me ne vado (I'll stop bothering you, then, and I'll leave.)
Lui: No, aspetta, se vai via mi annoierò davvero (If you leave, I will get bored for real.) E tra l'altro, ho dei lavori noiosissimi da fare e non ne ho nessuna voglia (And besides, I have some really tedious jobs to do and I have no desire to do them.)
Lei: OK, so che sono noiosa, ma non sarebbe meglio fare quei lavori dato che siano anche urgenti (OK, I know I am being a pain, but wouldn't it be better to do those jobs, given that they're urgent?)
Lui: OK, ora sei noiosa davvero. Mi sono ampiamente annoiato con questa storia (OK, now you are really being boring/irritating. I'm pretty sick of this thing), quindi forse è meglio se te ne vai... (so maybe it's better if you do leave.)
OK, ciao. Non ti voglio annoiare con un'altra delle mie storie noiose. (OK, bye. I don't want to bore you with another of my boring stories.)
