Hacer el primo

Hacer el primo
 

How can we say this in English?
Hacer el primo means to be a little bit silly because you' re to good to people. In a dictionary I found To be taken for a ride, does it make sense?

To be taken for a ride
-and-
To be conned

These both mean that someone has taken advantage of you (by lying, deceipt).
You've been taken (for a ride).
You've been conned.
You've been tricked.
You've been had.
You've been bamboozled.

Si hacer el primo significa que se ha sido engañado, da igual.

Yes, it does make sense.

The builder took me for a ride by persuading me I needed a complete new roof, when all I needed was a few new tiles.

A very common expression in Tenerife :eek:

Edit - oops, cross-posting. Must type more quickly

There is also a British slang usage for the word "mug" i.e. a gullible person; dupe; fool.
2. inf (ingenuo) mug
Cambridge Klett gives these examples too.
he hecho el primo: he pagado 50 euros por esto = I've been taken for a ride: I paid 50 euros for this
¡no seas primo! = don't be such a fool!

En este caso, el estafador es the conman/grifter.
La víctima es the patsy/sucker.
