Cuando tú vas, yo vengo

Cuando tú vas, yo vengo
 

This expression is a synonyn of No me la das, meaning that no me enganas, por mucho que lo niegues se que no es verdad.
English?

1)Oh yeah? Then you go first. (only in a situation when someone is trying you to do something)

2)Tell me another one:rolleyes:

I think number 2 is the equivalent.
