To accidentally expel liquid shit while farting.
I bent over too quickly earlier and splash farted in my kecks.

I spilt gravy on the kitchen floor, it looked like I'd suffered a splash fart.

When a female lets one rip while squatting down for a piss, usually causing the stream to splash!
Aoife was so drunk last night, carried her to the toilet were she started to splash fart all over the bowl!
