1.
To be obliterated, annihilated, raped*, emasculated, or otherwise beaten, typically in a video game, in such a phenomenal way as to be comparable to the manner in which Gendo Ikari, a godlike character from the popular anime Neon Genesis Evangelion, would "own" someone (most commonly Shinji Ikari).

*can also be applied to literal/statutory rape, as in the case of Rei Ayanami.
