Deliberate exaggeration, which no one takes literally, to emphasize a feeling or a situation.
In Romeo and Juliet
Love's heralds should be thoughts, / Which ten times faster glide than the sun's beams
Juliet says that thoughts glide "ten times faster" than the rays of the sun. The exaggerated number conveys the impatience of someone waiting for news who finds any delay unbearable.
Act II: The garden and the wedding, Juliet
That 'banished,' that one word 'banished,' / Hath slain ten thousand Tybalts.
Act III: Mercutio, Tybalt, and the banishment, Juliet
There is no world without Verona walls, / But purgatory, torture, hell itself.
Act III: Mercutio, Tybalt, and the banishment, Romeo
