The Act of absolutely killing funny jokes or situations by attempting to back up the funny joke with a completely unfunny statement that preceeds an awkward silence. this act should be followed by someone else saying "Quinned It" to the quinner highlighting further how much of a dick that person is for ruining a funny moment.
person 1: (insert any funny statement here)
person 2: (completey unfunny shite comment)
person 3: "Quinned It"
Any situation like this should from now be refered to as Quinning
