Mermaiding 

A fandom in which a woman (or more rarely a man) either buys or makes a mermaid tail for the purpose of swimming in pools, lakes, or just posing on the rocks, usually while being photographed. Occasionally done with other mermaids.

Hannah got her new tail in last week and can't wait to go mermaiding in it.
