The sexual act, coined by Michael Edward Hickey and Joseph Michael Young, when a woman is on all fours betwix two males, one entering her vagina (or anus), the other through her mouth. The two men then lock wrists, and pull back and forth like old-time lumberjacks using a two-man saw. Often called an LBJ for short, popular in southern Illinois colleges.
Hey Michael, that chick looks like she'd be down for a LBJ, Shotgun anus!
Yes Joe, She's ripe for a lumberjack!
