Young men will do ‘t if they come to ‘t,
By Cock they are to blame.

– William Shakespeare

Hamlet, Act 4, Scene 5. Ophelia, in her madness, sings a sexually explicit song about a flightly young man who promises love and then backs out after a brief time. The lines suggest that she and Hamlet may have had a sexual relationship. They also echo the theme of exploitaton and oppression of women by men.
