A sexual identity characterized by a masculine male, who identifies as heterosexual, but when engaged in outdoor activities with other males such as fishing, hunting, shooting guns, archery, or hiking, sees no problem with giving/getting a blowjob from a buddy. The only rules are no hugging, kissing, touching, affection, and most importantly, to never actually discuss it.
