look up any word, like donkey punch:
Roflbnaroflatt (roful-banaro-flat) translates to "rolling on the floor laughing, but not actualy rolling on the floor laughing, all the time". This word is used to specify that whilst listening or watching something or someone, you cannot seem to stop finding humor in it/them.
Dad: "What are you watching?"
You: "Eddie Izzard, and its roflbnaroflatt"
