Spwad Edit Meaning

1.

A very hot fart that melts some shite as it passes through the lower intestine and proceeds out of the anus at high velocity spattering your underwear with it's payload.

Oh my God, that wasn't a normal fart, I've just done a spwad. Where is your lavatory? I need to clean myself up.

See diarrhoea, the shits, two bob bits
