Below is a scene from Modern Family, and Phil is Jay's son-in-law. Phil tries so hard but Jay never seems to accept him as a "manly" man, and this time Phil, after all sorts of shooting practices to prove that he can do what Jay might want him to do, actually shot a bird with a gun in front of Jay,
Phil: (proud, looking for approval) That oughta fix it, eh, Jay?
Jay: (looking unimpressed) You got a piece of it.
(And Phil is dissatisfied. He looks dejected.)
Is the phrase connoting derision? Like is it underestimating the achievement or something? How should I interpret it in this context? Thanks in advance!
