A typing quirk is a systematic method of typing, in almost all cases deviating from the standard usage of punctuation and capitalization, though grammatical rules are generally upheld. While the kids do not consciously choose their quirks, in the culture of the trolls, quirks are highly institutionalized, commonly going as far as using emoticons that more accurately represent the user's personal appearance, substituting letters in a fashion that convey aspects of the user's personality, and other varieties of personalization. The degree to which a person can control his or her quirk is variable and depends on the individual.
