An individual who always eats 10 trays of the NYCDOE free school lunch; An individual who begs others for their ID to get another tray of School Lunch
During Lunch Jayden and Casseem are always trying to cut eachother on line while Lindon and Tyler are pleading with the other students to hand over their school lunch and give it to them. All four of these schoolie demons had done this strategy since freshman year, learning from their mentors Leonardo and Escalade. Lartey, took notice and said to himself " Schoolie Demons are back at it again smh" as they continued to profusely ask others to get them the school lunch. Meanwhile Ahmad and Marlee insidiously slipped to the front without anyone noticing all the while Robert watched in horror, Appalled as to what humanity had became, rethinking of naming BETA - Schoolie Killer Academy.
