What is the word for when you say something like "I'm dying" but don't mean it? [duplicate]

Histrionics

2. (used with a sing. or pl. verb) Exaggerated emotional behavior calculated for effect. (American Heritage, found at thefreedictionary.com)

(I couldn't find my own interpretation of this word in any of the dictionaries I checked, but I think that your typical natural-born drama queen or prince doesn't always do it for effect. Some people do it for more internal reasons.)

Example:

I'm glad to be home. I'm exhausted from one of my students and his histrionics. I know perfectly well his jabbering about wanting to kill himself isn't true suicidal ideation, but I couldn't very well ignore it, could I?

Hyperbole - exaggerated statements or claims not meant to be taken literally

I was looking for a word to reflect a comment to a new Snow Patrol album. "The album is that bad I would send it to anyone for free".
I know its not life or death but the album is the pits. You should hear it!
