road load
Roadside fecal blowout; the need to blow out your ass on the road, to take an unexpected fast shit while driving.
"Oh my God, pull over, I got a road load comin' on!"
Road Load
When a vehicle cuts you off on a snow covered road and sprays salty white shit all over the windsheild.
Fuck that dude in that truck just sprayed me with a road load! Turn on the wipers
Road Load
The act of ejaculating while driving.
That 6 hour drive would have been super boring but I passed the time with a road load.
