Here at a university of political correctness, one may find "themself" used in an attempt to avoid assigning a gender to a person under discussion and yet wanting to form a possesive. There is a strong stigma against using the appropriate "itself" when allowing a non-gendered noun possesion.
During my education pre-college, "myself" was graded as an appropriate word that lends to a mature tone. But the sentence, "She and myself went bowling," and, "He gave it to myself," would not pass. It was more along the lines of, "As for myself," and "myself included."
The English language has always been one of incorrectness and mutability, however. As an interesting side-note, ebonics shares traits with archaic pre-modern English grammar and pronounciation.
Like mentioned above, mis-spoken cliches irritate me. The mis-use of "well" and "good" irritates me as well. Not yet mentioned, however, is the irritation caused by a narrow vocabulary. For example, college students should know the words "sensational" and "diffuse."
