What is Fill Up A Can?
1.
the bulimic equivalent to "smoke a bowl".
many bulimics look like they're taking a drink of something in a can, but are actually depositing small amounts of vomit into the can in the most non-attention-drawing way possible.
bulimic one: hey, I just ate way too much. I'm gonna go fill up a can.
bulimic two: have a Diet Pepsi
