A term to describe an act of intensionally enraging a group of people on an internet chat room or forum board. It's often used as a parody of Die Hard an action film from 1988, although instead of the protagonist climbing a tower full of armed terrorists he is climbing a tower of shit puns and all caps all in bold italics and font size 26, all while spouting memes and ridiculous opinions on a plethora of things.
