a YUF is a small jump made by two relatively insane people into each other, they run and jump into each other and shout YUF as they colide with pain.

The two states of being are as a human being, or a hungry ghost. Semi-regularly you need to ask yourself which you are. Sometimes it is human. Others, alas, it is hungry ghost.

The hungry ghost seeks validity outside of themselves. Someone pining for an indifferent ex is a hungry ghost. Someone who arrives alone at 6:30 on Saturday night to a pub is probably a hungry ghost. Obsessive checking of mobile phones, chat sites or networks are clear signs that one is a hungry ghost.

The best thing to do is just stay home and ride it out. Read a book. Find some good clean fun.

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.
