When shirts are tucked firmly inside your jeans, it is extremely homosexual. To stop this sudden abundance of homosexuality you must untuck them. This is done by firmly grasping your shirt with two hands and force them up with an upwards motion. This will free your shirt from your jeans and allow your jeans to take a long sigh of relief.
