Apparently, the word "snuck" has been in use since the 19th Century. To say there is "no such word" is erroneous. The word exists in common usage. Although the dictionary prefers "sneaked", it includes "snuck." Zeon is perfectly justified in using it.

Also, I would point out that you should have used parentheses instead of commas to separate the words "it's capitalized" from the rest of your sentence. Otherwise, it's a sentence fragment.

Plus, your capitalization correction for the term "grammar nazi" is not a cut-and-dry issue, either. Some prefer to reserve the capitalized term for references to the Nazi party itself, and to keep the lowercase for general terms. Others insist that both words should be capitalized, which makes a little more sense to me than your suggestion. However, I disagree. There may be rare times when it could be used as a title, or for emphasis, but it's most often a common noun.

A grammar nazi is not referring to a member of the Nazi party, or to misguided adherents of the Nazi principles. But, it works nicely for emphasis in such exclamations as "You, Sir, are a Grammar Nazi!" (note that I also capitalized Sir, for emphasis)

A normal adult mouth has 32 teeth, not counting wisdom teeth. Not everybody gets those. I imagine that extra white spot at the back could be a wisdom tooth.

Send money? Seriously? Not for her. For the bear, maybe.

Yes, it sucks what happened, but if you can't fund your own adventures, even with mishaps, maybe stay at home.

When you encounter a bear, you get away. If you can't easily, then you make as much noise as possible. She is actually endangering her own life by trying to distract the bear from her kayak, when she could have stayed in her cabin and waited out the so-called "attack". Totally irresponsible.

Few and far between, though.
