I don't know if you are referring to sayings in English like: "Who rattled your cage?" or "Don't get your bowels in an uproar!" or sayings in Spanish. For the latter, the next time you are in Spain, visit a bookstore (or book stall) and ask for a
Refranero Español. The one I have was published around 1960 (Madrid, Aguilar)
Madrileños speak in refrains (not unlike Londoners). When you ask about them they reply
'es un refran' o 'es un dicho'. I think you may find the one about getting your Knickers in a wad may come from the Cockney.
