How to make tight waist on jeans larger?

Something i just tried a minute ago... if the pants are just a little too tight, just try putting them on without wearing any underwear and start doing squats. Do like 10 of them and on the last one hold it for like 30 seconds. if that's not good enough you can pull the jeans down to the broadest part of your waist/butt and repeat. Worked just fine for me =)
