HVL 

Head Volunteer Lifeguard, also known as a "Pool Rat". A HVL spends a lot of time at the pool, usually equal to or very close to the hours of the paid lifeguards even when it is closed due to thunder and/or rain. The HVL often knows many or even more pool rules then actual lifeguard staff members. In addition, the HVL often spends more time in the guard office talking to paid lifeguards, then in the water.

Julia: "Why not?"
Nate: "Because I am the HVL?"
Julia: "Oh...your the Head Volunteer Lifeguard?"
