The act of using some type of plastic card (Visa, credit, school, debit, gift, etc) to snort cocaine.
Me and My friend thought of the word when we found out that my friend used his School ID card to do it, just scooping it in a line on the card, and "scanning" it across your nose.
"Man bitch, I was scanning last night, and that shit was rawww."
"That guy scanned last night. Afterwards he became a crazy nikkuh."
