31 Fuel

31 means masturbation in Turkish and is used frequently by Turkish people. (The term "31" was first used by Ottoman Empire to define the name of masturbation which is "el çekmek". During the time, writing "el" (means hand in Turkish) looked like the nuber 31 so local people strated using the slang.)

Like the term "nightmare fuel" this term can be used to express a love and an attraction to something or someone -using it on a person might be kind of creepy unless it's your homie or smth-
