Where does the expression “the Jig is up come from”?

proboly some rapper, Ive never heard of it.

The jig is up means the dance is over – its time to go home or to stop things, you know? Dance, as in dancing around something – maybe the truth… The dance of lying to people or swindling people or whatever… A cute – and old – saying.

It is believed it originally referred to the end of either a ‘trick or game.’

Today it is defined as a scheme that’s been ‘revealed or foiled,’ ‘all chances for success are gone,’ esp. when applied to ‘risky or improper’ strategies.
