A sneak attack, similar to a "cock block", but instead of preventing someone from getting lucky, the perpetrator of the "pearl Harbor" maneuver is trying to steal the person away.
Male #1 is trying to make a move on Female #1, but due to much fluid consumption, must depart and use the restroom. In Male #1's absence, Male #2 moves in and makes his move, thus committing the terrible crime known as "The Pearl Harbor"

When your sleeping next to a chick who has her back to you and you start to massage her back and act like your just being nice to her for no reason, and then you just hit it from the back while she least expects it. You see, its a sneak attack which hints the name Pearl Harbor. She will never see it cumming.
My chick is all pissed off at me because I gave her the pearl harbor while she was sleeping last night.

When one person of asian ethnicity invites several of his asian friends to a party, who in turn invite several more asians, creating a mass of asians (much like extreme elimination challenge) who invade the party, taking it over and making all the non-asian guests quite uncomfortable.
Guy 1: Dude what was with all the asians at that party last night?

Guy 2: We shouldn't have invited Alex, he Pearl Harbored the fuck out of that party.
