To guestimate is when you have no idea about something, but you don't want to sound like an idiot.
Its a careful combination of guessing what the topic is about and then estimating the correct answer.
Also another thing you could add to this is a statistic, as it makes your answer sound more valid and believable!
Paul: so what do you think of the whole el nino phenomenon?
You: in your head, what the FU*K? Thanks paul!
Now you guestimate

Step one guess... Ok so it sounds kinda mexican, doesn't nino mean grandchild? Ok so its something to do with mexicans, sounds like a dance...
Step two estimate an appropriate answer...every one likes dancing and mexicans make good food so I'm gonna like it.
Make up a statistic... 89% of americans think its a positive movement.
Helpful tip: you could always be wrong so answer briefly and not to in depth!
You: well I feel its a positive movement that's changing the world in a dramatic way, 89% of americans see it in a favorable light!
In your head- BOOM how u like me now paul!
