brain donor

Extremely stupid person, someone who acts as if they've already donated their brain to science--before they die. Clueless. Dumb as a rock.

brain-donor card

A euphemism for marijuana. Instead of explicitly asking a random person for an illegal substance, it is used out of politeness and legal reasons.

Old hippy guy: Hey man... you got a brain-donor card?
Young dready: A brain-donor card? What the fuck is that?!
