A smothered wagon is similar to a covered wagon but you shit under the blankets instead of just fart. One could also shart under the blankets to qualify as a smothered wagon.
I tried to give my roommate a covered wagon but sharted and gave myself a smothered wagon.
Kind of like a dick wagon. Instead of a wagon full of dicks, tis a wagon full of pricks. Otherwise known as a Pierre or a Leeham. If you are called a prick wagon, you should just cry for the rest of your life.
riding the woof wagon is the equivalent of riding the struggle bus except it is only said by the dankest of dudes not a slew of unintelligent teenage white girls
