Pertaining to the wang. Of or relating to subjects regarding the wang. Also, amazingly cool, but still terribly stupid stupid. The word "wangular" is in and of itself, quite wangular. Used exclusively to describe things related to homosexual males.
Have you seen that new pink pinto Freddy bought? It's kinda wangular.
Sorry Laura, but I don't think Jimmy would be interested in you. He's of the more wangular persuasion.
