Contrary to sarcastic (usually called "ironic") humor and culture,
post-sarcastic humor and culture genuinely shows admiration/appreciation for something, to the point where you are completely unashamed of liking something that others may consider embarrassing.
Example of sarcasm: wearing a Phil Collins t-shirt because you actually *
don't*
like him, and you're wearing it in a way that mocks him.
Example of post-sarcasm: genuinely enjoying Phil Collins enough that you would wear a Phil Collins t-shirt and sing his
music in public.
