Slang term for a wheelchair, particularly a wheelchair that is used by an extremely fat and overweight person. The term has absolutely nothing to do with those ox-driven wagons that farmers in the old days used to haul grain and stuff.

2. Ayyo ni'a, if you keep being all over that greasy shit like a Tri Delt on cake, someday you gonna be so fat that yo' legs can't even support you and you'll need an ox cart to haul yo' lard ass around!
