Question about the show mad money?

on this show, Cramer was talking to the CEO of Unilife and he said that he "endorses it as a speculation". what exactly does that mean?|||Investing and speculating are very different. The latter is high risk guesswork that a price of something will go up in the short term, and still be desired.
