Chilango slang is full of imagery and color. A great example is the expression tú nomás di rana ... (too-noh-MASS thee-RAH-nah), which means "you just say frog ..." To the uneducated listener the expression has to be completed with ... y yo brinco (ee-JAW BREEN-coh), which means "... and I leap" (like a frog).
This expression shows how game a person is for a particular plan. It is used as a most emphatic agreement with that plan.
Gema: Estaría a todo mecate ir este fin a Tepoz. Ya tiene un rato que no vamos.
Yolanda: Pus tú nomás di rana.
Gema: Wouldn't it be nice to go to Tepoztlan this weekend? It's been a long time since we last went.
Yolanda: Just say the word, girl.
