To Lesher is to speak with authority on 100% of a
problem while only understanding <5% of the
problem.
Leshering describes the actions of an
incompetent, poor leader who is so completely misinformed and emboldened by the misinformation, they believe they're actually a smart and powerful leader.
TO LESHER (verb)
1) Dude, let's keep it simple and stop getting emotional.
Don't lesher me. Let's calmly break down and discuss the actual facts of the matter!
2) That
guy had no awareness, knowledge, or context of what he was
talking about. He just got all blustery and began to lesher the hell out of everyone until we all got annoyed and tuned him out!
