The statistically anomalous tendency for the telephone to ring while you are having a shit. Extensive studies have shown that the phone of any individual has, at any given time, a 500% higher chance of ringing while its owner is evacuating his/her bowels than during other common everyday tasks such as masturbation, hoovering and chimping. Some schools of thought consider telecoprolism to be a subset of the Sod's Law principle. The others don't really consider such issues to be a worthy use of academic time and resources.
I was just settling down for my morning log and got telecoprolised by the bank again. Bloody telecoprolism, eh?
