Call me verbose (oh, you’d be the first, I promise), but I would be ecstatic if the response of “This.” would fall out of fashion and thusly die in a fire.
With so many options for speaking coherently, do we really have to do this? I mean, it’s no “huh”, but it is worse than “I agree.” I’m a great fan of verbing nouns (which some would call pretentious word usage), but even I think it sounds a little embarrasingly cute.

This.
(I do like the idea of falling out of fashion and into a fire. It leaves a lovely mental image of wafer-thin models up a tree, trying to avoid the flames below.)
That.
Man, you guys are funny. I never would have predicted that response!
Why do I not have an animated eyerolling icon?
Hey, somebody had to do it.
The other thing.
related: i absolutely adore the phrase “die in a fire.” the images it conjures are great (:
Yeah, I feel guilty for enjoying DIAF. :D
I hear you and agree. How do you feel about “Word”, which seems to be the same sort of thing?
What about “word” with an adjective in front of it, such as “tyrannosaurus WORD”, which I sometimes use?
I don’t get “word” very often, except verbally perhaps. I think I enjoy it much more as a greeting (a la “word, peeps!”) than I do as a “right on.” Either way, it doesn’t squeeb me like “This.”
word, nerd
The Other.
I don’t believe I’ve heard it much outside of So Long, and Thanks for All the Fish and the occasional lj comment. But your entry is disproportionately (snort-out-loud) amusing because, in working on my grad school applications, I have been obsessively digging through my Frankweilerian files looking for a series of college-written concrete poems in the shape of human genitalia starting with one called “This” (so named because it could not rejoice in the sobriquet that many euphemise as “the c-word.”)
Erm. Yeah, I gotta work on having that life.
