Hyperbole

/haɪˈpɜːr.bə.li/ noun easy

Exaggerated language not meant to be taken literally, used for emphasis or effect.

When she said she'd told him a million times, that was pure hyperbole, not an actual count.

Memory Trick

'Hyper-' means beyond or over (as in 'hyperactive') — hyperbole pushes a statement way beyond the literal truth purely for dramatic effect.
