Corp Por is the incantation
of the spell energy bolt
in Ultima Online
. The spell is of widespread usage, especially during PvP
, so after playing UO for a significant
portion of time, you will hear 'corp por' quite a bit.
The phrase itself has developed a colloquial
meaning in online games
as a way of describing imminent danger
or a warning that something bad
is about to happen.
