lay out on
lay out on (someone or something)
To spend or invest a certain (typically large) amount of money on a particular person or thing. A noun or pronoun is used either before or after "out." But with students or their parents laying out tens of thousands of dollars on college tuitions, many have begun to question how necessary those degrees are in the first place. I'm not keen to lay several hundred dollars out on a house we're only renting.
