1. To make a broad statement based entirely on ignorance.
Statement could also be based on rumor, and/or negative or positive popular
opinion.
2. To project your
opinion of a particular subject as what everyone else's
opinion should be.
Example 1. Person 1, "Brah, Circuit City is lametastic" Person 2,
"Do you have anything to base that on?" Person 1, "Well..
no." Person 2 "Dude, you're so clemtatious!"
Example 2. "Hey man, do you like
Metallica's new stuff or old stuff
better?" Clemtatious guy says, "Dude,
Metallica sucks"
To avoid being clemtatious, he could of said "Dude, I
don't like
Metallica"
