If you wind up in the emergency room because, say, you were trying to launch bottle rockets out of your anus, you can expect to hear this term thrown around.

The opposite of the 'midas touch'. Rather than everything one touches turning to gold, to have the 'faecal touch' means everything one touches turns to shit.

'How's work going at the moment mate?'
'Just awfully dude, I definitely have the faecal touch. It doesn't matter what I seem to do or how hard I try, everything I am involved with completely fucks up and turns to shit.
The act of sitting in a position whereby the anus is located above the head, possibly in a bath. Whilst suffering from acute explosive diahrroea, the culprit sprays their own body and face with liquid faeces. Most often seen on the shock website www.tubgirl.com
