A specific process in which
one person, preferably male, shits in their partner's left nostril, thereafter continuously sodomizing the remaining nostril until said shit "galoops" out at high velocity in a manner very similar to a "shit rocket."
One hopes it will not hit
one's left testicle.
Person
1: "I performed a super
dooper pooper galooper last night, and barely dodged the projectile!"
Person 2: "Yeah, you're lucky, I attempted that procedure and it
made a hole in my bed!"
