It would be chanting the name of a local sports team. This is something mayor Parker of Philly has managed to fuck up, chanting E L G S E S instead of E A G L E S because she is dumb as a rock and drunk as a skunk
She used to be an English teacher too! Alas, the two most left leaning candidates in our mayoral race split the vote and without ranked choice Parker managed to win 😭
OP explained the Parker aspect of the joke, but as for the Jets, their fans chant “J-E-T-S JETS JETS JETS!” in a similar fashion to how Eagles fans chant “E-A-G-L-E-S EAGLES!”
