to handle a hot potato, to deal with a tough problem
Restou pra mim descascar o abacaxi, ninguém vai me ajudar!
It's up to me to deal with this tough problem, no one will help me!
To descascar o abacaxi is literally "to peel the pineapple," and the image carries the meaning: the fruit has a hard, irregular, spiky rind, so peeling it without hurting yourself takes patience, technique and time. That everyday difficulty became a metaphor for any thorny problem nobody wants to handle.
