That is from south park eric. The episode was about the changing of the meaning of the word. Fag does not refer to homosexual males like it used to. younger folks now use the word to reference annoying and inconsiderate people.
The word "gay" now means "lame", stupid, etc.
The Harley reference was in the episode and the metaphor behind the story.
the episode was from 2009. Most of the kids nowadays don't watch it. They are too preoccupied with social media and/or to stupid to understand the satire.
Most kidding aside...Pops really enjoys Blade! Loves hanging with his grandson Dano', at Blade AND at Comic-con in Orlando for 3 days!! He's a rock star with the nerds also!! Everyone wants a Grandpa like him!
