Dude the assembley was high schoolers doing 20 second dances. High schoolers dance provocatively these days they don't waltz its a natural progression of dancing or whatever.
He found an appropriate time to go overboard and make it really really funny. Again one can make a point that even without a dildo a 16 year old girl shouldn't be dancing like that in front of 1000 people. But with the dildo she got shown up for being a ho.
That nigga picked a perfect time to do it shit was hilarious and bad ass.
Teach at the end was mad funny too you could see he wanted that thing used on him. Lame fucks like those teachers deserve to be laughed at by strangers on the web.
