WaterBed

When your bed is drenched in cum; usually after the act of edging or orgasm denial.
Could also happen after many rounds of fucking.

Dude, that new technique you showed me had me in a complete waterbed last night. I think I need another mattress...

California Waterbed

When a man causes a woman to squirt, but pinches the labia so the vaginal cavity fills up with fluid.

I went to Pelosi's nephew's waterbed store to purchase a new waterbed. Little did I know, the owner porked me on his inventory and gave me a California Waterbed.
