The term is usually used in a positive situation when one has achieved success or when someone is feeling sudden happiness or enthusiasm. Many using this term may feel an unusually strong connection to America. Therefore, people yelling out this term will sound like wannabe yankees. Fuk yeh! has become increasingly popular since the film Team America was released.
