Shakey-Finger Gun Answer 

When a person has an answer to the question that is subjective, their hand shakes drastically in order to show their excitement to answer the question. This is followed by an 'I suppose' and then the answer. Another following statement is a 'Depends on the context'. Another way to get the attention from answering the question is a statement of 'ahhh-sir/ma'am'.
