using household liquids (paint thinner, sharpies, etc.) to get high. In its most common form, the liquid is applied to a bandanna and put over the nose and mouth so one is breathing it in constantly. Though extremely stupid, it does give a good high.
"Why is that kid wearing a bandanna inside?" - Kid 1
"Dude, he's spooking! Look at how loopy he is!" - Kid 2
