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!"

when you're holding up your phone and making faces at it, as though you are taking a selfie, but you're really taking a picture of the person across from you or the wall or anything else that seems interesting but you don't want to be caught dead taking a picture of.
