How about "epitome."
"This situation is the epitome of FUBAR."
If you want a verb, there's "epitomizes", but I like the noun better.
Yet another answer: quintessence, sense 1, "A thing that is the most perfect example of its type; the most perfect embodiment of something."
A related term is paradigm, sense 1, "An example serving as a model or pattern; a template."
encompasses
Means to entirely cover something.
In the same register as 'FUBAR', one would use the phrasing:
This situation is totally FUBAR.
I've always liked "embodies" and "incarnate."
"This situation embodies FUBAR."
"This situation is FUBAR incarnate."
"exemplifies" is a great term for this, as it refers to providing an example.
illustrates and depicts will also work here.
This situation defines FUBAR.
If you want to completely embody the meaning of a term then I would reason that the situation is a definition for the term so therefore it defines it.
Giving an example by illustration or comparison by epitome seem to be one step removed from a complete embodiment or definition.
If you're not keen on the verb then go this way:
This situation is, the definition of, FUBAR.
When you're talking about someone rather than something or some situation, you can use personifies or one of its other forms....
Charles is the very personification of narrow-mindedness.
As an alternative to all of the above.
Boil it down.
This situation is FUBAR.
I think the word "is" is what what you're after.
