mannaggiammammt
Portmanteau of common expression in neapolitan slang "mannagg' a mammeta", vaguely translatable to "damn your mom".
When you hai già fatto la valigia - and for "fatto la valigia" I mean "incastrato tetris style every fottuto purchase and possession, until the valigia's contenuto got back to singolarità quantistica" - and scelto every item to indossare from now to tomorrow but the maglia you picked makes you feel like you fell in un vulcano and so mannaggiammammt.
