Splesp, noun or verb.
To splesp is when a female goes for post-coital urination and once seated, expels gas from her vagina thusly forcing out the collected semen inside of her. The word was derived from the noise created when a woman splesps.
I had great sex last night but when I went for a piss I did the loudest splesp ever! He must have cum about 2 litres in me
