More over the previous definitions, the "I Win Button" in the world of EvE Online is a pre-nerf expression referring to the Titans "Doomsday" Device, as it is a area of effect weapon, causing massive damage to everything around it.

As such it was called the "I Win Button" since (if anyone survived) the remnants were easily mopped up, nomatter how many they initially were.
Yeah, we were totally bringing that Titan down with our massblob, until the pilot hit the I win button and we were annihalated.
