Effing and Blinding 

To let forth a torrant of obscenities and give vent to a stream of profanities. Quite simply, have a bloody good swear.

In the kitchen, grandad had stubbed his toe and all round the house, one could hear the old man effing and blinding. The vicar turned quite crimson.

Total Efficiency Coefficient, (T.E.C.)

T.E.C. Is the closest possible approximated measure of energy expended in any biochemical and or socioeconomic process from start (A) to finish (B) generally portrayed in calories and represented as a percentage in decimal form.

i.e. A boat carrying a load from South Africa to Beijing has a stand still value of (Xcalories) @ point (A)=Xcal. divided by the total calculable energy in calories expensed in “fuel”, “labor”, “payload loss” and “mechanical breakdown” used upon reaching point (B)=Xcal. where {Xt.e.c. = (A)Xcal. / (B)Xcal.}.

*Xt.e.c. = Total Efficiency Coefficient, (T.E.C.)
