Made from the meme and horrible company name "B.J. Champion". If someone says your mom has a champion van, basically they're calling your mom a cock-sucker. This also can apply to anyone who is not your mother.
Student: "Mrs. Woods, do you drive a champion van?"
Teacher: "What?"
Other Students: "OOOOOOOOOHHHHHHHHHHHHHHHHHH!!!!!!!!!!"
Teacher: "What?"
Other Students: "OOOOOOOOOHHHHHHHHHHHHHHHHHH!!!!!!!!!!"
