Unfit For Purpose 

This expression originated with the Royal Navy where stores or equipment were found to be damaged, wouldn’t work or could not be used for the purpose for which they were intended. The expression quickly found wider usage and is now applied to not just stores and equipment, but to organisations, designs even concepts. It can also be applied to co-workers if they are not doing their job properly and, in extreme cases, used as a put down where someone is a complete arsehole and unsuitable to be considered part of the human race.

Malcolm you are unfit for purpose.

An expression often used by men online who want to know the name of a certain video or person so they can store it in their spank bank.

It's synonymous with saying, "so I can fap to this later on."

Can anyone tell me the name of that girl in the video with the big boobs? For research purposes, of course.
