guesstrapolate

To make a prediction or extend a line of thought toward a conclusion based on uncertain or insufficient information.

Since there are so many planets like earth in the universe, there must be other intelligent life, but I'm just guesstrapolating.

I can only guesstrapolate that given her history of blunders and her ignorance of history, the Constitution, and geography, Sarah Palin could never be elected president.

They say serial killers have a history of animal abuse, fire starting, and bed wetting, but that's really only guesstrapolating

Isn't everything just guesstrapolation?

guessterpolate 

When reading values from a table and the value you want to look up does not appear, instead of calculating the value properly using interpolation you guess what the value would be but don't round it off, add a couple of decimal places to make it look legit.

Na, I didn't have time, so I just guessterpolated.
