Chicle y pega

Chicle y pega (CHEE • klei • PEH • gah) literally means "chewing gum and sticks". It is used to imply that a strategy might work but it is not guaranteed. The idea is that such strategy "might be like chewing gum and stick."

Example:

Rutila: Compré una serie completa de la lotería. Si ganamos, vamos a ser millonarios.
Nicanor: Chicle y pega y no tendríamos que chambear de nuez en toda nuestra vida.

Rutila: I bought a lottery ticket. If we win, we'll be millionaires.
Nicanor: If that happens, we won't have to work again for the rest of our lives.  

The árbol del chicle (chewing gum tree) in Coyoacán is a popular attraction for tourists (who take pictures of it) and locals (who get rid of their chicles on it)
