Applesaucin' is slang for using the
valid argument form "Modus ponens," sometimes called "affirming the antecedent."
Origin:
"We can clearly
see the validity of Norcross’
s argument as he correctly employs the logical device of affirming the antecedent (or as we call it in the streets: applesaucin’)."
"He's just applesaucin', but his
first premise is
false."
"Applesauce all you
want, but your shit's still unsound."
