When the winter weather is so bad that there is a lot of snow/slush on the side of the road. Sloppage occurs when you swerve your car to splash that mess on people going by. I'm sure accidental Sloppage occurs, and for that we apologize... we were truely aiming for someone else.
Dude #1: What happened to you?
Dude #2:(covered in dirty slush) I was on my way to class and I totally caught royal SLOPPAGE. Had to skip it and change.
The weather was so crappy that when I saw that jackass Dave walking, I knew I absolutely HAD to cover him in SLOPPAGE with my jeep.
