"Yeah, I can nig-rig 'er."
Attempting to perform a McGuyver-esq procedure and making a repair or modification with available resources, usually in the ghetto.
Making something out of the incorrect
or non-intended parts and/or materials.
Final product resulting in a shoddy, half assed solution that inevitably breaks after inital use.
My muffler was dragging so I nigrigged it with some some pantyhose I ganked from some tool who was trying to rob a 7-11 with a paintball gun.
Why you got to nigrig that shit all the time? (When you see your boy trying to patch the rip in his pants with some scotch tape.)
Donnel: That's a nig rig!
