Pookake is when several people perform a variation of an act called "Bukake" where instead of ejaculating on to someone's face, they just take a fat shit on them instead.
Person 1: "AHHH! THOSE BIRDS JUST SHAT ON MY FUCKING FACE!"
Person 2: "hehe lol, get pookaked dumbass"
Similar to a bukkake, but way more intense. Consists of a group of men (at least 20 or more) that take separate turns shitting on a girls face, hair, and tits. The girl that is getting shit on usually rubs the fecal matter all over her entire body. A pookkake requires a pookkake tarp because a pookkake can be quite messy. Most girls have several orgasms during a single pookkake session.
Guy: Hey sis, do you want to be the focal point of a pookkake tonight?
It's like bukakke, but with poo instead of jizz. Like a group assplosion in the face.
Hey Rod, Larry... what are you guys doing Friday night?? Oooh, want to come over to my place? We're gonna pookakke Sandra (you know how she likes the warm aroma in her nostrils).
