The act of ejaculating in someone's helmet while it is left unattended, then getting them to place it on their head. A practical joke particular to the military.
Joe left his helmet in the truck so I rubbed one out in it then he put it on, it was the perfect turtle wax.

An awfull smelling mixture of ass fluids and sweat that collects in an individuals upper ass crack on hot summer days. Also common of nerds to accumulate large quantities of turtlewax while playing videogames in thier sweatpants.
