Kylie Monroe going full sheet- the act of being suddenly, explicitly, and personally racist or bigoted to a culturally marginalized group or individual, usually a form or component of an assault
Syn: "saying the quiet part out loud"
The thing about old racists is that many of them have been in cushy jobs long enough that dog whistles are a second language so it's rare to catch them going full sheet. On the bright side, they'll be dead soon!
