Después de aquel largo viaje, decidí dormir a pata ancha toda la mañana.

[morbrorper]

English Translation

After that long trip, I decided to sleep like a log all morning.

Is dormir a pata ancha used in Spain? I’ve seen dormir como una piedra in some other cloze.

[Daniel42]

I don’t know either of those. I’d say "como un tronco’. You see speech balloons in Mortadelo or wherever with a log being sawed when someone is sleeping.

[MistahMartinez]

I haven’t heard that one, only domir como un tronco as Daniel mentioned, or dormir a pierna suelta.
