My favourite phrase for describing adolescence / the teenage years is the Spanish estar en la edad del pavo. It means “being in the age of the turkey”

A Danish expression for when it’s very windy is “it’s blowing like half a pelican.” An Estonian version is “wind so strong it could blow a pig on to its hind legs.” But my favourite is one I heard in German that translates to “it’s only wind when the sheep no longer have curls”
