I conjure thee by Rosaline’s bright eyes,
By her high forehead and her scarlet lip,
By her fine foot, straight leg and quivering thigh
And the demesnes that there adjacent lie,
That in thy likeness thou appear to us!
– William Shakespeare
Romeo and Juliet, Act 2, Scene 1. Mercutio calls out for Romeo, who has disappeared into the Capulet’s orchard in a mission to find Juliet. But Mercutio thinks that Romeo is still pining for Rosaline, not realizing that he is over her and in love with Juliet. Since the audience knows this, this is an example of dramatic irony. Since he is something of a joker Mercutio summons up the "dead" Romeo by Rosaline’s beauty and physical appeal. He uses sexual innuendo to talk about her trembling thighs and the parts that lie next to them.
