(adj.) Describing the state of someone's work computer after co-workers prank it if it's left unlocked. Often the desktop wallpaper, Windows event sounds, IM away messages, email signatures, etc. are changed to a My Little Pony theme.
"Aw man, I left my computer unlocked and it now it's ponied. Now I gotta spend 30 minutesgetting it back the way it was."
owned but worse. originated when I made it up while talking with friends in early 2004 while discussing the hilarity of people typing pwned instead of owned. i made the jump and pronounced it with a "p" and it evolved into ponied. which was fitting since we know a guy that goes by pony, and he thinks he owns everyone. again, i want to reinstate that i made this up, not this other n00b prof. walrus.
To be sucked into defending someone's base because they fell asleep unshielded mid raid and began to be raided themselves.
JT pony Dr.Zarkhov and i were raiding XCOM the other nightfighting xcom for their friends goods when pony fell asleep unshielded MID RAID! Had to defend him for 2.5 hours. We got ponied.
