The act of receiving road head while driving off-road so as to allow
the bumps in the road
do the work for you.
Caution: Driving too fast while receiving
off-road head can have disastrous results. 15 mph is the maximum recommended speed.
Erin said she was too tired to give Michael
road head so he turned his 4x4 down an old
dirt trail to get some
off-road head instead.
