Alright, Literates! It's experiment time! LINE UP!

The word "encrescent" does not exist in any English dictionary. I just pulled it out of my ass on the spot for a writing project I am working on. The English language is flexible and allows for this kind of thing, within reason. If you make up a word that is not self-evident such as, say, gumber-fombling, you have to explain its meaning.

Gumber-fombling: Verb. Something that a man you really do not like does to your mom, noisily, right in the next room, and there is nothing you can do about it without causing problems so you might as well just go downstairs and watch TV in the hope that it will drown out the terrible, terrible sounds.  

Example: That dick who works at the convenience store down the street was totally gumber-fombling my mom last night. That sucked.

If the word is self-evident such as Buttmongering-bananaphobe, (one who mongers butts and is terrified of bananas), then you probably don't have to explain it, at least not in such detail as the previous example. Of course, this begs the question of "how do we know what is self-evident?" To me, that word is very obvious, maybe because I invented it. However, what if someone else reads it as buttpeddling cockphobe? After all, to monger is to sell or peddle and banana is a euphemism for cock. See how this can be problematic? Word-pioneers may run into problems of actual definitions versus colloquial definitions, connotation, context, cultural bias, all the way down to the way individuals perceive meanings.  

Now, with all that in mind, I am going to throw a few sentences at you. If you could please read them then answer the questions afterward, that would be very helpful to me.
______

Terro climbed the wall of rocks encrescenting the pond and jumped into the water.

Alexander awoke to find himself encrescented by his giant, absurdly fluffy dog.

The serpent protectively encrescents her young as they play in the grass under her watchful eyes.

The gelatinous creature will subtly begin to encrescent its prey, moving in such slow, careful increments that its nefarious intention goes completely unnoticed until it suddenly tightens into a ball.
______

QUESTIONS:

1.) After reading the sentences, can you think of any other words that would also work? For example, in sentence two, enwrapped and in sentence three, coils around. The first sentence could be restructured to read Terro climbed the crescent of rocks. In the last sentence, encoil might.... wait..... encoil is not a word? WAT. It should be, goddamnit.

2.) Do you think inventing words like this is stupid, smart, or are you ambivalent?    

3.) If you saw a word like encrescent as you were reading, looked it up, and found that it was invented, would you be angry? Would you not care? Would you think the author is creative? Other?

4.) Please briefly describe these scenes in terms of what you think encrescent means.

If people respond to question four with things like Terro climbed the wall of yodeling vaginas or The gelatinous creature will subtly begin to molest your toaster oven, well, that is a good indicator that I should think about not using the word encrescent, stop making up words, and just maybe stop trying to pretend I can write.

Anyway, thanks, if you can spare the time.
