Sadly, "wtv" is not a legitimate word, so there are no synonyms to offer for it. However, if you meant "whatever," there are several synonyms that could be used to convey a similar sentiment, such as "anything," "anyway," "anyhow," "regardless," "notwithstanding," or "nevertheless." These words suggest a dismissive attitude towards a topic or situation, indicating a lack of interest or concern for it. They might be used in casual conversation as a response to something that is perceived as unimportant or insignificant. While they share a similar meaning to "whatever," each word has its own unique connotation and tone that can influence how it's perceived.
