(noun)
With origins on college campuses, it’s a cash withdrawal system which allows the financially broke student to access fast money by way of placing, generally, 3 unopened soupcans into a pillowcase, finding an unsuspecting lender in a compromised and singular situation, braining them with the soupcan pillowcase, and then once they are dropped liberating them of any and all valuables and cash on their person.
Not only did Jordy invent the soupcan ambush—-he perfected it. I swear to be such a destructive fucker he could load up a few of my cans of soup into his pillowcase, slip off into the night, locate victim he deemed appropriate, drop them, and return back to the dorm in less than an hour with serious bank and the soupcans undamaged.
