If the need to change the form of the greeting is realized, then all that remains is to connect self-control and use more literary options. On the other hand, forms like "gratuti" or "chewylista" are a tribute to fashion, which is quite changeable. These expressions can be replaced by other buzzwords ... Are you influenced by this fashion? Then don't worry ... The habit of using gratuti will go away by itself.
Attachment to the meme, no more. On an instinctive level, a person adapts to society so that society itself can help him in the future. As with many problems, there is a great way to find an alternative. For example, an outstanding "hello" or some cry from your favorite piece. However, the memes in "2K16" came out rather mediocre and they get the stigma of a boyan zashkvar much earlier than the same memes last year.
