That'd be a question for the General Tag thread, since you're not suggesting a definition...
...but [yes, there are](/tags?tq=*pibby*). You can find these things out for yourself by searching on the Tags page linked from the top navigation bar. A very useful feature is that an asterisk `*` will substitute for any amount of text, so if you're not sure what an entire tag is but you know what part of it needs to be (eg. "pibby") you can put an asterisk at the start and end, like I did, to show all tags with "pibby" in it.
