A bevy of seaworthy gashes.
At the beach elbowing each other, "Check out the twatilla at 3 o'clock, man."

By the pool casting furtive glances, "Don't look now but a twatilla has just begun laying out lawnchairs."

Just passing by on a boat in the lake, "Up periscopes and spyglasses dude, looks like a twatilla preparing to jet ski in our wake!"
