The short bursts of pain one experiences when they need to take a dump or 'crap'. Similar in length and style to contraptions that a women will experience during labour before birth.
Wife: 'Arghh these contraptions are killing me'

Husband: 'I had Indian food yesterday and the toilet's blocked. My concraptions are way worse'
