To "Party Pop" someone is just another way to "Cock Block" them, only better.
Right when someone is about to get some, you go in and ruin all their fun with a bunch of party poppers.
Note: Since no normal person really carrys around party poppers on a daily basis, this works best during New Years parties.
Guy: "Jordan is totally about to get laid right now."
Girl: "Lets go party pop him :D"
Next Day
Jordan: "Fuck you all right in the ass for party popping me last night."
