Straight from Merriam-Webster, folks. http://www.merriam-webster.com/dictionary/modus+operandi

The idiot that said, "<i>operandi</i> is not a Latin word" is incorrect and needs more thumbs down. That entry should be removed.

My M.O. is to make the author of definition #2 look like a fool. That is what I am "all about."

I educate people and correct mistakes in "wiki" slang dictionaries by editing and making my own entries that state corrections of previous ones, when aforementioned entries are stupid. That is my M.O.

My M.O. is humiliating people who think they know more than they do even though both they and I are anonymous.
