The term 'STOCK ANSWER' can be represented by two crossword solutions: MOO (3 letters) and IMALLOUT (8 letters). MOO is a sound that cows make, and is often used to represent a lack of originality or creativity. IMALLOUT is an acronym for 'I'm all out', which is a phrase used to indicate that one has no more ideas or solutions. Together, these two solutions suggest that a STOCK ANSWER is a response that is unoriginal and has been used many times before.
