During missionary sex, when the women begins to move around too much, you place your arms underneath hers in a double underhook fashion to prevent her from sliding any further.
Dude, Mike was fuckin' this bitch and he was pokin' her so hard he had to double underhook her so she wouldnt move around so much.
