The yellow vehicles that you see on the road every morning and afternoon which bring children to and from school. Can be a literal nightmare sometimes, as little kids are screaming or adolescents are yapping at each other. Don't be late to the torture vehicle, or else you may be late for school!
Mom: Son it's time to take the bus to school today!
Son: But mom, I don't want to take the torture vehicle! It sucks... Can't you or dad just drive me there instead?
Mom: No, I gotta get to work, and your father is busy. You have to take the bus.
Son: Don't you mean torture vehicle?
*mom sighs and facepalms* It's called a bus, kiddo.
