An onomatopoeia of Arabic origin that indicates tiredness, inability to cope with stress, task at hand or life in general, or an overall lack of (social) energy. It is an umbrella term for "I just can't". The more the letter 'u' exists in the word the higher the degree of yuffness. So yuuuuuf means you are more tired than yuuf.
