finger check check 

The act of forcibly stopping the finger check by grabbing the perpetrators middle finger and bending it awkwardly and painfully backward. When performed successfully, it not only prevents the completion of the finger check, but also permanently dissuades any thoughts the perpetrator might have to attempt such a maneuver at a later date.

As Byron's hand slipped into Laura's pants, Laura quickly grabbed his middle finger and bent it backward until Byron cried out in pain. "What was that?", asked Byron. "My finger check check", replied Laura.

The act of a person (typically teenage), sticking his/her finger down the pants of a lady. Then sneakingly smelling ones finger, to see if one would go down on the lady.

Yo dude, did you perform the finger check?

finger check 

A computer "bug" that is the result of the operator pressing the wrong keys. Derived from "finger" (obviously) and "check" (meaning a computer-detected error).

Similar to "operator malfunction".

Yeah, the operator made a finger check and lost this week's payroll.
