What does it mean when this girl said on her Facebook profile she said: I'm kind of monotone?

[August]

What the hell does it mean?

[Ami Z]

Maybe she meant you're very simplistic/simple and plain, chill.
Don't take it to offense, its not an insult.

[Dennis S]

She's asking if your think she is boring.

[louisa]

Did she mean monotonous? Because that would mean dull and repetitive, but monotone is a noise haha

[Wolfe]

She could be describing the way she speaks and presents herself, i.e. a monotone voice. She could also be calling herself boring and repetitive (monotonous).

[Froggy]

She means that she's boring, a single tone of voice repeated with different words.

Sameness or dull repetition in sound, style, manner.
Having no colour to her personality.

She sounds boring - she says so herself.
