A Muddy Coles is the act of taking a sexual parter to the frozen section of a Coles supermarket and vigorously fingering their anus.

This can be performed as a duo act known as the Double Muddy Coles. Two hands, two anuses.
Me and the missus went to grab some frozen fish but I ended up slamming her with a Muddy Coles.
