Starting with a conclusion first, fudgy logic is
the process of using faulty and sometimes made up
assumptions, reasoning and justifications, to arrive at the said foregone conclusion.
Similar to
circular reasoning, except the in-between steps are faulty or fudged up.
1. Joe insists that 1+1=10 because he does arithmethic in binary, and therefore through fudgy logic
deduction, no other number-base should exist.
2. To Jane's and Spot's
surprise, Dick ate all the lasagnia, because his fudgy logic dictated that since they let him eat first,
no one else wanted it.
