Well I'm from Houston, and down here "barred out" means to be messed up on Xanex "bars." Bars are the most potent of Xanex pills in front of blue and purple "footballs." Usually you drink on them and get really fux0rdz.
a adjective popular in Atlantic Beach and Greenville that is used to described someone who is mentally lacking from using xans or other causes, the term is a more friendly and less offensive way of saying “retarded”
Man 1: “Dude I can’t take my friend Zane anywhere, he’s too barred out
Man 2: “Yeah I can tell by the way he was talking about how the birds are spies, definitely barred”
