Trash is the thing that all Grouches love most in the world. Their hometown, Grouchland USA is a living embodiment of the saying "1 man's trash is another man's treasure", as it incorporates trash of all kinds into the very fabric of the city's architecture & economy. This is the idiom to which Grouches always stick.
Anything a Grouch likes can be described as anything dirty or dingy or dusty, anything ragged or rotten or rusty or trashy. It has been proven as a fact that getting new trash is 1 of the few things that can truly delight a Grouch, even though they immediately try to hide their joy, as being happy is 1 of the many things that Grouches hate.
While all Grouches express their love for trash, Oscar the Grouch has shown everybody how much he loves trash on several occasions with his signature song "I Love Trash" on Sesame Street. 1 tradition is, whenever Oscar sings "I Love Trash", his signature song, he is always shown at his trash can, & nowhere else. Oscar's girlfriend, Grundgetta loves trash as much as he does.
Trash is also the 1 thing that a Grouch would NEVER get rid of. Oscar considered doing so in episode 3815 (& later episode 3959) cause his pet elephant Fluffy took tap dancing lessons but his trash can was too full. However, obviously, Oscar just couldn't let go of his trash. He & Fluffy, however, eventually came to a fair agreement.
