When a man (or woman) builds up a large amount of gas and releases an extremely large, liquidy fart onto another persons face or genitals.
Carmen is into some pretty weird shit. She made me eat Taco Bell today and when we went back to my place later that night she told me to tell her when I had a fart coming on so I could give her face an Ocean Spray. It got her real horny though.
First, in order to do the "Ocean Spray" you must have a female partner/girlfriend/rape victim who is able to squirt when cumming. Wait until she is on her period to either fuck/finger her until she cums, and watch the crimson tide spray all over the place.
When getting a nice ass rimming, wait until a puddle of saliva builds up and blast a nice air biscuit at her. The spit will spray in her face like waves crashing on the shore
