Students can be so creative sometimes.
And other times…not so much.
The word ‘beat’ takes its roots from the Greek philosophers. In the agora, Greeks would gather to exchange thoughts about politics, social constructs, and the plight of the masses. Often, members would be ostracized for holding dissenting opinions. These unfortunate dissenters would be deemed ‘beatus.’ Essentially, this was the Greeks’ way of saying, “You suck.”
I’m just messing with you. That was all crap.
But, seriously, students use this word to assert their unearned, self-constructed dominance. A male student saying to another male, “That shirt is so beat!” is essentially saying that Goodwill will soon have another garment to sort using their incomprehensible system.
A female student claiming that, “This class is beat,” is making it known that the teacher should expect no more effort from her for the day. In many ways, this is a self-reflective term; students that use the word are often holding a mirror to their own shortcomings.
In short, ‘beat’ means ‘lame.’
A good teacher example: “Not having the entire week of Thanksgiving off is so beat.”
