smaller taur
This is used when two (or more) beings are together and the smallest one happens to be a taur compared to an anthro character, a human, et cetera who is also present. This is typically used for couples with a notable size difference but can be non-romantic and non-sexual. The opposite situation is labeled larger taur.
