“Fuqn” is often used as an intensifier, similar to the usage of words such as “very,” “really” or “extremely.” If someone says, “That was fuqn hilarious,” for instance, they will mean it was really very funny. “Fuqn”, however, has a more emotional quality. Used to convey excitement, frustration, surprise, or strong personal feelings. It may be used in informal speech as an alternative for intensifiers, but it is regarded as informal slang and is not appropriate for professional, academic or formal speech.
