i've seen the "grass " movie and they show a soldier making a shotgun to his partner with an actual shotgun, looks powerful!!!...i believe that's where it all started as the apellation "shotgun" and no it's not gay doing a shotgun to a guy, if he fucks you in the brown while doing it, THAT's gay! otherwise my bro and i and smoking partners are trying to kill ourselves with powerful shotty, that i believe it's what is all about doing it to a guy, you know, competition...
