During a threesome (with two guys and a girl.. or three guys..... but seriously two guys and a girl), two males stop their motions, yell out "Chinese fire drill!" then proceed to jog around in a circle three times. After this, the two males swap positions and continue on, after a high five of course.
Jimmy and bobby where happily pig roasting
Jane, when Jimmy suddenly shouts "Chinese fire drill!". Both Jimmy and bobby stop what they are doing immediately and run in circles around Jane three times. After this is completed, Jimmy and bobby swap positions and give each other a high five in successful completion of the Chinese fire drill.
