This line is said in the very first episode of a cartoon show, Total Drama Island.
This is the first time the characters are introduced. I assume the comment is about their clothing being out of place.
But I can't find out what "T.O.ed" means.
Chris Mclean (The host) says:
We told them they'd all be staying at a 5 star resort, so if they seem a little T.O.ed, that's probably why.
Looks like T.O. could be tick off:
Definition of tick off
transitive verb
1: to make angry or indignant
the cancellation really ticked me off
(M-W)
The language is flexible enough to allow us to say T.O.’d. This kind of usage is not unprecedented (e.g. K.O.’d for knocked out). We understand T.O.’d to mean ticked off.
It seems to fit, as the plot suggests the characters are deceived:
Total Drama Island is set in the fictional titular reality show, which follows the competition of 22 unsuspecting and unknowing teenagers at Camp Wawanakwa, the most rundown, bug-infested, disgusting island located in an unspecified area in Muskoka, Ontario. The campers participate in competitions and challenges which get more insane and dangerous each week to avoid being voted off the island by their fellow campers and teammates.
(Wikipedia)
They were expecting a 5-star resort, but ended up in rundown dump. Hence, they were T.O.’d, ticked off.
To me, tick off is a milder version of piss off. Also, we sometimes use acronyms or abbreviations to soften or censor a word or phrase (e.g. F off, a steaming pile of S, an M-Fer, that S.O.B.). The usage of abbreviations like this is informal.
I was able to find a clip here (the line in question begins around 2:40). The host talks in an informal, slangy way that appeals or mimics the way teens and young audiences speak. The choice to use T.O.’d here, I think, not only serves to soften the language, but also to sound catchy or slangy (maybe even jocular).
All in all, the usage of T.O.’d makes sense in this context. In general though, I’m not sure how common T.O.’d is, but I think P.O.’d (pissed off) is somewhat common.
As in Em's answer, it's short for "ticked off", which in turn is a common euphemism for "pissed off", meaning angry (as an adjective or rather participle) or "made angry" (as a verb), to avoid saying the word "piss" (urine/to urinate).
"P.O.'d" is also a euphemism of sorts for "pissed off", and "T.O.'d" seems to be following the same pattern. It might even be poking fun at avoiding the word "pissed" by (rather pointlessly) avoiding the word "ticked" in the same manner.
"Teed off" maybe?
teed off (idiomatic, slang) Annoyed, upset, angry
It's not a phrase you hear that much these days (in the UK at least), and I've never heard it as an acronym, but it seems to fit the context.
