When someone sleeps farts and usually has no idea that it happened.

Sleep farting

A slimy or "slippery" fart. Often one of those symptoms associated with your common hangover or gassy and/or upset stomach.

A fart that escapes during sleep, sometimes waking the slarter him(her)self.

Other word for slut.

A term used to describe a woman so unbelievably dirty and skanky, that the resembles the stereotype of both a slag and tart. Using far too much make-up and fake-tan, she can be mistaken for a wedding-cake as well as an orangutan. Stay away lads.

'Slart' too tarty to be a slut, and not good enough to be a tart.
