The act of displaying your penis while still wearing pants. Usually accomplished by unzipping the pants and exposing the penis. This is often done at party's or in public as a joke, but can also be utilized as a means to proudly display your penis to potential sex partners to ignite arousal and attraction.
That guy over there is Trouser Trouting, he's got his dick hanging out of his zipper in front of Mary. I bet she's going to hook up with him.
