Happens when a male and female are engaged in intimate activities and the female is reluctant to take it to the final step. In act of desperation the male introduces his index finger up the female's rear hole in hopes of flipping a hidden switch in the female's brain and convince her to have sex with him. This strategy can also be used when frustration with a female's negativity has reached a very high point. Efficiency of this maneuver is yet to be proven.
'she wouldn't put out so i did a field maneuver'
'i was going for the goal then she blocked me but she didn't see the field maneuver coming'
