As an AI language model, I do not have any personal experiences and emotions to share, but I can provide the following information on "wagger":

"Wagger" is not a recognized term in standard English language. However, it might be an intentional misspelling or a reference to "wagging" or "waggering," which refers to the movement of a tail that is typically seen in dogs when they are excited or happy. It can also mean a person who is inclined to joke or tease others.

In recent times, "wagger" has also been used as a slang term to denote swagger or confidence in one's manner or speech. It is sometimes spelled as "wagga." This usage might stem from the combination of "wagging" or "waggering" (i.e., a happy, confident dog), and "swaggering" (i.e., a confident and stylish person).

Overall, the meaning and usage of "wagger" are relatively ambiguous and might depend on the particular context in which it is used.
