"Welcome home" is a complete sentence. Welcome serves as an imperative in much the same way as "Stand up" is considered a complete sentence. This is NOT an utterance or an exception to any rule
In the book, "Commands: A Cross-linguistic Typology" found on Google books, page 179, the example of "Welcome home" is given as a non-command form of the ...
It can be a case of verbing, but using trip for the sense of travelling or going on a trip is non-standard and would be strange (see @EdwinAshworth's comment for other formulations that may be strange).
Trip is also a standard verb, meaning to (make someone) fall due to an obstacle, to switch on/off an electronic circuit, to move with quick light steps and ...

If someone is being negative, feeling that they can't accomplish what they want, you would respond with something that matches their mood: "nothing is impossible".
You deny their negative attitude with another negative.
But if someone is being hopeful about what ...
