The Brief: A "sneaky link" is a sexual partner who someone keeps secret.
Someone’s “sneaky link” is a person they’re secretly hooking up with. They may be “sneaky” because they’re having an affair or just because they want to be discreet. Typically these relationships are casual and more sexual than they are romantic. A “sneaky linkup” is when people meet to hookup in secret.
