mca girls are not baddies. they are flat I guess. mca boys don't like mca girls, only sb baddies. the girls in sb are baddies, so they love sb girls. additionally, mca girls say they grind, but they never grind. they don't even know what grinding is. overall mca girls suck and we hate them a lot. they only got into mca because of the gender balance, they are not even smart. they belong in the kitchen. mca girls are the reason every mca guy is gay.

Person #2: "...MCAS Syndrome."
