At Sea Level Club

Similar to the mile high club in all ways except that this club is joined while on a cruise ship.

Wow the cruise was amazing; my girlfriend and I finally joined the at sea level club. This time we truly did move like the motion of the ocean!

Below sea level

A phrase that is a synonym for keep it on the down low.

So, it turns out that I was the one who shot Bambi's mom, but lets try to keep that below sea level.
