Guesstimate

Idiotspeak for "I don't have a fuckin' clue."

In its original use, this portmanteau is rather clever. According to Wikipedia, statisticians first used the word guesstimate in the 1930s to more accurately differentiate estimates derived from inadequate data. Sadly, I have met people who use guesstimate and estimate interchangeably (of course going with the more lenient definition in all cases). I think the more insidious problem is that media outlets authoritatively deliver junk stats as estimates rather than guesstimates.

Stupid indeed, but has its uses like " Ah guesstimate that nobody on de durn grizz list has been to the dentist since Tampa Bay done won the Super Bowl."

Not too bad in terms of frequency- but this garbage office-speak of the highest order. I literally cringe when I hear a minion talk like this and hit 'em with the dreaded- "Don't talk like that in front of a client- ever."

As stupid as it sounds, C'mon, I like this one!

Its not in as heavy use anymore and I like that fact. It is a silly word...

I guesstimate that, like, you know, a lot of people like use this one...you know?

It is a strange combination of guess and estimate but I too have used this in the past but not so much now. I try not to butcher the English language (on purpose anyway) and try to avoid slang terms or sayings such as this.

Although I find myself using this occasionally, I know I shouldn't. It just sounds weird but cool at the same time.
