Ghettoland ISD

Any school district that has less money or more minorities than the one you attend. (Term is usually associated with a closet racist or classist speaking from a position of power in a school.)

John: In Houston schools, they allow phones. Why not here?

Teacher: If you wanna be the pures— I mean… whitest— Wait… Best school around, you don’t act like Ghettoland ISD over there!
