torpedo

torpedo - cheat sheet (I believe a torpedo is always "against class rules" in Chile whereas this tool is sometimes allowed in classes in the States.)

Marco: ¿Hiciste el torpedo para matematicas 4?
Anibal: Se lo tengo listo.
Marco: Está filete, ¿dejáme hacer una copia?

Did you make a cheat sheet for math 4?
I've got it ready.
It's sweet, can I make a copy?
