When a group of bros, preferably 3, wants to signify their bromance they touch the scrotums of their fully erect penises and bind the base of shafts together with a rubber band. Thus creating the trifecta of a bromance known as the Brouquet. Or a bouquet composed of penis shafts.

Note: A binding pressure of roughly 10 Kpa is recommended to avoid unintentional castration.
