Anyone heard of this.. I told my sister in law to take me to the store so I could get hot Cheetos and she goes "okay hold on wait till my show goes on commercial, don't give me styes pleeeease" lol I was like what are you talking about and she says "you get stys if you don't get a pregnant girl her cravings" lol I never heard of that but it's funny.
