"Kharalona" is used to define the often horrible European football club commonly known as Barcelona.
"Khara" in Arabic means shit. Combine that with the already existing shit that plays for Barcelona, and you have a very catchy word.
Ex.1 "Hahaha! Did everyone see Kharalona get hammered today?"
Ex.2 "Wow, I always knew Ronaldinho was overrated....no wonder why he plays on Kharalona."
