MacGuyverism
When you're so good at fixing stuff with whatever's around you that you make a fool out of anyone who tries to stop you. No tools needed. Just a lot of swearing and a little bit of magic.
Used a paperclip and a piece of gum to fix the entire school's electricity during lunch.
Turned a broken phone into a working bomb just to annoy the principal.
Fixed my broken bike with a sock, a pencil, and a curse.
