n. the act of finding someone/something to blame for a problem

(from a TV ad for HD television)

A word one may scream while propelling an object through the air at alarming speeds, heights, and etc.

An extremely expressive word that can be used in many situations.
On one end of the spectrum, "yeet" can be bellowed with a full, guttural sound whilst lobbing an object furiously to assert authority (great for water balloons and empty containers). On the other hand, "yeet" can be used gently, like the faint brush of a butterfly's wings as it crosses one's lips, as one completes a difficult task (i.e. boss in a difficult game, tough question on a math test).

n. Everyone thinks they know what it means until they realize they have no f*cking clue

Said when throwing something for no reason whatsoever.

To throw with mad force
