used to describe a large amount of
something that's seen as
disgusting, gross, and/or discomforting
can be
pronounced in anyway but it's mainly said as "reh-ck-tear-ee-ous".
the word (tear) in in 'rectarious' is said as in "there was a tear on the letter", not your salty crybaby water droplets.
p.s: akane really did take a rectarious shit.
